Use the form y=mx+b, where m is your slope of the line and b is your y-intercept.
A. y=-x+7
B. Move 3x to the right side and divide the equation by -6 to get y=0.5x-2
C. Move 2x to the right side and divide the equation by 4 to get y=-0.5x+3
D. Move 9x to the right side and divide the equation by 5 to get y=1.8x
You can figure out the slopes from there.
