Question

Write an equation in slope-intercept form for a line with m = −1/2 that passes through the point (2, 3).

Answer 1

Slope intercept form is y = mx + b
M, which is the slope is, -1/2

Plug the given coords in y = mx + b
It would be 3 = -1/2(2) + b
3 = -1 + b
Add 1 to both sides
4 = b

I think you can figure the answer out using b = 4 and m = -1/2

Answer 2

y=-1/2x+4
