Question

6. Compare the line passing through the points (-2, -9) and (4, 6) with the line given by the equation

y=2/5x-4.
А They have the same slope.
B They have the same x-intercept.
с The two lines are
perpendicular.
D They have the same y-intercept.

Answer 1

First find slope
(6+9)/(4+2) = 15/6 = 5/2
Y = 5/2x + b
-9 = 5/2(-2) + b
-9 = -5 + b, b = -4
Same y intercept

Solution: D
