The process for simplifying depends on how you are going to give your answer. I cannot thank you enough for your help. Most students, since they have already labeled a and when finding the slope, choose to keep that labeling system.
You can also check your equation by analyzing the graph. I liked that I could ask additional questions and get answered in a very short turn around. You can take the slope-intercept form and change it to general form in the following way. They really helped put my nerves at ease. How do you know which one is the right one?
You may be wondering why this form of a line was not mentioned at the beginning of the lesson with the other two forms. What is your answer? The process for obtaining the slope-intercept form and the general form are both shown below. What will we look for in the problem?
You also have TWO points use can use. Web sites like justanswer. Now you need to simplify this expression. Given Two Points When you are given two points, it is still possible to use the point-slope form of a line. If we re-write in slope-intercept form, we will easily be able to find the slope.
Traffic on JustAnswer rose 14 percent If you need to practice these strategies, click here. The first step is to find the slope of the line that goes through those two points. You would first find the slope of the given line, but you would then use the negative reciprocal in the point-slope form.
Those have x and y variables in the equation. That means our line will have the same slope as the line we are given.
The variables x and y should always remain variables when writing a linear equation. Writing an Equation Given the Slope and Y-Intercept Write the equation for a line that has a slope of -2 and y-intercept of 5.
As we have in each of the other examples, we can use the point-slope form of a line to find our equation. You will NOT substitute values for x and y.
If you need help calculating slope, click here for lessons on slope. To learn more about parallel and perpendicular lines and their slopes, click here link to coord geometry parallel As a quick reminder, two lines that are parallel will have the same slope.
They truly know what they are talking about, and they actually care about you.1. Write an equation of a line perpendicular to line AB below in slope-intercept form that passes through the point (7, 6). Line AB is shown.
A is at 0, /5(9). Write the equation for a line that has a slope of -2 and y-intercept of 5. NOTES: I substituted the value for the slope (-2) for m and the value for the y-intercept (5) for b.
The variables x and y should always remain variables when writing a linear equation. A line has a slope of negative 3/4 and goes through the point 0 comma 8.
What is the equation of this line in slope-intercept form? So any line can be represented in slope-intercept form, is y is equal to mx plus b, where this m right over here, that is of the slope of the line.
The slope-intercept form of a linear equation Earlier in this chapter we have expressed linear equations using the standard form Ax + By = C.
Now we're going to show another way of expressing linear equations by using the slope-intercept form y = mx + b. Question Write the slope-intercept form of the equation of the line shown in the graph. Please show all of your work.
Please show all of your work. (-6, -2) (4, 3). Equations of lines come in several different forms. Two of those are: slope-intercept form; where m is the slope and b is the y-intercept.
general form; Your teacher or textbook will usually specify which form you should be using. In the examples worked in this lesson, answers will be given in both forms.Download
