Question

determine the slope m and y-intercept b of the given line: x=-1/2y + 3

Answer 1

you can re-write this equations as:
x-3=1/2 *y
or y= 2x-6
1)slope - number in a front of x m=2
2) y- intercept means x=0
if x = 0, then y=-6 , (0,-6)

Answer 2

I keep loosing signs... didn't see "-" in a front of 1/2....
easy to fix - change the sing :
x-3=- 1/2 *y
or y= -2x + 6

you can finish it now

Answer 3
