What is the equation of the line that passes through (-1, 4) and ( 2, -8) written in slope-intercept form?
A)Y = -4X
B)Y = 4X
C)Y = (1/4)X
D)Y= (-1/4)X
The answers tell you the y-intercept is zero, so all you need to do is choose the appropriate slope. Since y/x = -4, ... .. selection A is appropriate.
