To change this into standard form, we start by moving the x-term to the left side of the equation. We know how to use the point-slope form, so the final answer is: The key to expressing in standard form is in how you arrange these three terms.
In this case, you simply multiply both sides by the denominator 3 to put all of the numbers in the numerators: Some students find it useful to label each piece of information that is given to make substitution easier. Hence the need for both. Therefore the slope of this line is 2. It is an important point to remember that if there is not explicitly shown a value for A or B in front of the x or y, then A or B is understood to be 1.
Notice that in the chart, the 2 grey sections slope and y-intercept are the two numbers that we need in order to write our equation. As you can see, point-slope form is nothing too complicated. Well, let's look at the point slope form and see if we can show how you get the standard form from it.
What is your answer? Let's do both for clarity With algebra we have: Thankfully, the principles of the algebraic rearrangement remain the same, so if you understand how to do one conversion, the other should be a similar-tasting piece of cake. Here you will have to read the problem and figure out the slope and the point that is given.
Although you have the slope, you need the y-intercept. We need the x-term to be positive, so multiply the equation by -1 to get our answer: If you are comfortable with plugging values into the equation, you may not need to include this labeling step. This relation means that we know the x and y coordinates of an ordered pair.
You can remember that the slope is the rise change in y divided by the run change in x or you could calculate this form from the point-slope form of a line. We know we are looking for a line parallel to.

If you would like further explanation on some point, or a graph to make this clearer, write back and I would be happy to give you more help.
If you need help rewriting the equation, click here for practice link to linear equations slope. You will NOT substitute values for x and y. I know that this is a rate and therefore, is also the slope. All we need to do is substitute! Find the equation for this line in point slope form.
As in, if I say you have x, you understand that you have 1x. As we have in each of the other examples, we can use the point-slope form of a line to find our equation.
We will do one more quickly and you should be able to answer the rest. Math Finding the Equation of a Line Date: Your final result should look like: We can now write our equation! Equations of lines come in several different forms. If you are given slope and the y-intercept, then you have it made.
If you are given slope and a point, then it becomes a little trickier to write an equation. Although the numbers are not as easy to work with as the last example, the process is still the same.
Point-Slope Calculator Many functions to try! In fact, the two equations are easily obtained from one another. Example 1 You are given the point 4,3 and a slope of 2. Find the slope using the slope formula. I would suggest trying both and seeing what you think.EXAMPLE 2 Rewrite each equation in Standard Form.
EXAMPLE 1 Write an equation in Slope-Intercept form given the slope and a point on the line. a. m = –4 and passes through (–1, 3) EXAMPLE 1 Write an equation in point-slope form of the line that passes through the given point and has the given slope.
Point-Slope Form (Practice Worksheet) Write an equation in point-slope form of the line that passes through the given point and has the given slope. To write the equation of a line, all you need is one point it passes through and the slope.
That's because the point is (x, y) and the slope is m, so when you substitute these values into y = mx + b, you just have to solve for b. Example4: Write the equation of the line with a slope of (-3/4) that passes through the point (0,6) in standard form.
First, we have to write the equation of a line using the given information. We know m = (-3/4) and b = 6, so we use slope-intercept form, y = mx + b to start. Step by step tutorial on how to convert the equation of a line from slope intercept form to Standard form.
Several examples and practice problems with pictures. Slope Intercept to. Practice: Write each equation in standard form. 1. Obiecfive To write an equation of a line given its slope and a point on the line Problem 2 Complete the model to write the equation in point-slope form.
