Question

L1 passes through (1,4) and (3,-1) while L2 passes through (3,2) and (5,-1). find the angle from L1 to L2.

Answer 1

first, let us identify the slope so our equation will look like y=mx+b, we need M which is the slope

Answer 2

how?

Answer 3

can you teach me step by step "?

Answer 4

the slope of each line can be found by using the point-slope formula:
\[y_2 - y_1 = m(x_2 - x_1)\]

I'll show you for the first line, then you can do similarly for the second line on your own
I take the points, (1,4) and (3,-1) and plug them in to the right spots in the equation
-1-4 = m(3-1)
-5 = m*2
-5/2 = m [here is the slope for the first line]

you try it for the second line which has points, (3,2) and (5,-1).
