Question

I did all the steps but got stuck at one part... help!
Write an equation of a line that passes through the point (3.5, 7) (-1, 20.5)

Answer 1

did you find the slope?

Answer 2

I got 13.5 over -4.5 .

Answer 3

@satellite73

Answer 4

so what are you stuck on?

Answer 5

your slope is correct by the way

Answer 6

Okay that helps I thought it was wrong. So after I got the slope I plugged that and the point (3.5, 7) into y - y1 = m(x - x1)

Answer 7

I got stuck because how would I multiply 13.5/-4.5 by -3.5?

Answer 8

write everything as a fraction

Answer 9

An improper fraction or just 13 1/2?

Answer 10

improper, then you can cancel stuff out

Answer 11

But then that would be a fraction divided by a fraction right?
