Question 81057: I am having major problems understanding slope and intercepts.
How do I write an equation for the following:
Slope = -2 y-intercept = (0,4)
Slope = 5 y-intercept = (0,-2)

The key to knowing what to do here is knowing that the slope intercept form of a line is highlight%28y=mx%2Bb%29, where m=slope and (0,b) is the y-intercept.
:
Slope = -2 y-intercept = (0,4)
Therefore m=-2 and b=4
highlight%28y=-2x%2B4%29
:
Slope = 5 y-intercept = (0,-2)
Therefore m=5 and b=-2
y=5x%2B-2
highlight%28y=5x-2%29
:
Happy calculating!!!
