Is my answer correct? if not please correct me

Using the given equation y-3 = 3/4(x+2)


Give Y a value and then solve for x:


If y = 0 the equation is now:

0 -3 = 3/4(x+2)

Solve for x:

-3 = 3/4x + 1.5

-4.5 = 3/4x

x = -4.5 / 3/4

x = -6


So the first point would be (-6,0)


Now make x 0 and solve for y:

y -3 = 3/4(0+2)

y-3 = 0 + 1.5

y = 4.5

So the 2nd point would be (0,4.5)


You are close, but the dot you have on y=4, needs to be moved up to 4.5.
