Question

Complete the equation of the line through (3,-1) and (4,7)

PLZ I really need help
I´m at this type of things

Answer 1

y = 8x – 25

Explanation:

Answer 2

8x-25=y

Explanation:

All we need is slope. (y2-y1)/(x2-x1). Now we just substitute values--(7+1)/1=8

Now we can plug in the slope as m, so

8x+b=y

Now all we have to do is plug in a point value and find B.

24+b=-1

Subtract 24 from both sides

b=-25

CHECK

32-25=7

Correct
