Geometry HELP!!
Given two lines, prove that if the slopes are the same and the y-intercepts are the same, then the lines coincide. Assume two lines do not coincide (~q). Then, either their slopes are different or their y-intercepts are different (~p). Since ~q → ~p is true, p → q must be true. Therefore, if the slopes and y-intercepts are the same, then two lines coincide.

What type of proof is illustrated above?
A.proof by contradiction
B.proof by contraposition
C.proof by direct method
D.proof by law of detachment

I mean, well, I don't feel bad per se, I don't feel great either

jdoe0001 · Answer

I mean, he should know what the answer is, or go through the textbook and get it, it'll take more than 2mins to find it, so, 2 mins is not quite reasonable
