Question

WRITE THE EQUATION OF LINE IN SLOPE-INTERCEPT FORM. 1. A line through (1,2) ; slope is 7​

Answer 1

y=7x-5

Explanation:

You have to use y=mx+b and plug in (1,2) in y and x so you have 2=7(1)+b and then you multiply 7 and 1 which you get 7 so now your equation is 2=7+b and subtract 2-7 and you get -5. So your equation is y=7x-5
