write an equation in slope-intercept form for the line through the points (-2,4) and (2,0) ??

Question

hero · Answer

1. The slope intercept form of a line is y = mx + b
2. Insert each point, one by one into the formula to get:
    4 = -2m + b
    0 =   2m + b

3. Add both equations together to get:
    4 = 2b

4. Isolate and solve for b to get:
    4/2 = b
        2 = b

5. Find m:
    0 = 2m + b
    0 = 2m + 2
    -2 = 2m
    -2/2 = m
        -1 = m

Therefore the slope intercept form of a line is:

y = -mx + 2

@VeritasVosLiberabit , you should have added 4 to both sides to solve for b
