The hypotenuses (the long side of a right triangle) of similar triangles ABC and DFA both lie on line k, as shown. Demonstrate whether the slope of line k is constant between points C and D. Use the leg lengths of triangles ABC and DFA in your answer.

Aline has a slope of and a y-intercept of –2. what is the x-intercept of the line?

Ill mark the brainliest if you me with the these three questions 7,8,9
