Given ab//dc
prove triangle abe is congruent to triangle dce
this is for my homework

∠ABE is congruent to ∠DCE; we know that AB||CD, so these are alternate interior angles.
∠AEB is congruent to ∠DEC; they share only a vertex, so they are vertical angles.
The two triangles are similar due to AAA; all 3 angles are congruent so they are similar.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
