What is the FIRST step when you are asked to write an equation in slope-intercept form and given two points?
Step 1: Use the two points to find the slope of the line.
100
The points (0, -1), (1, 0), (2, 1), (3, 2) lie on the same line.
What is the slope of the line?
m = 1
200
Write an equation in slope-intercept form using the given information below.
Point on the line (0,-3)
m=-2
If you didn't notice, the point (0,-3) that was given is the y-intercept (b).
y=-2x-3
200
Rewrite the linear equation below into slope-intercept form.
x-y=3
y=x-3
200
Find the slope of the line that passes through the set of points (-7,3) and (3,-1).
Simplify your answer completely.
m=-2/5
300
Write the equation of the line in slope-intercept form.
y=1/3x+1
300
Rewrite the linear equation below so that it is in slope-intercept form.
2x-3y=6
y=2/3x-2
300
Is the equation below a direct variation?
2x+y=0
Yes! The rate of change is -2
y=-2x
