Question 148360
1) Graph the equation and identify the y-intercept:  y=5x-9
2) Graph the equation and identify the y-intercept:  y=1/2x
3) Graph the equation and identify the y-intercept:  y+x=-6
4) Graph the equation and identify the y-intercept:  x+4y=12

You'll have to do the graphs, I see no way for me to do them here.
#1, 2 and 3 are in the y-intercept form, y = mx+b
1) the y-intercept is -9
2) the y-intercept is 0
3) the y-intercept is -6
4) x+4y=12
4y=-x + 12
y = -x/4 + 3
The y intercept is 3
