Question 876754: write an equation in slope-intercept form for the following:
Change in y is 3 while change in x is -6; line contains point (0,9) Answer by harpazo(655) (Show Source):
You can put this solution on YOUR website!
The slope is- 3/6 or -1/2. The point given is (0,9).
We need to the point-slope formula.
y-y1 = m(x-x1)
y1 = 9, x1 = 0 and m = slope which here is (-1/2)
We now plug and chug.
y-9 = (-1/2)(x-0)
y-9 = (-1/2)x
y = (-1/2)(x) + 9
Done.
