c

Answer 4

d

Answer 5

for each equation do this:
put x = 0, look what you have for the y-value. this will give you the y-intercept (0,y0) of the line.
put y = 0, look what you have for the x-value. this will give you the y-intercept (x0, 0) of the line.

that way you can verifiy one of the two lines of each graph is that particular line.
