Question

given y=mx+b, determine m and b. line t passes through O, and the angle from t to the line 4x-7y-28=0 is 45 degree

Answer 1

O=origin?

Answer 2

yes

Answer 3

I think line t is y=mx+b ?

Answer 4

we already know our line is in the form y=mx
since it goes through the origin

Answer 5

I will do a rough drawing of things...

Answer 6

I think we need to first identify the slopes of each line.

Answer 7

slope of line 1 is m
slope if line 2 is 4/7
