Ade and abc are similar which best explains why the spike of the line between point a and d is the same as the slope between points a and b

Spike of the line between A and D is the same as the slope between points A and B because ADE and ABC are similar.

Explanation:

ADE and ABC are similar triangles means that they have same internal angles while may have different size. But due to same angles, the ratio of their sides is same.

As slope depends on the angles of a triangle which in turn depends upon the ratio of the sides of a triangle, two similar triangles must have same slope for corresponding sides.

y > 1/3x

y < = -x + 4

hope this : )
