Question

Write in slope intercept form an equation of the line that passes through these given points (-1,-1) (1,5)

Answer 1

Final answer: Y=3x+2
Since you are given 2 points. You will plug the points into this formula. X2-X1/Y2-Y1. This will get you your slope. Then you will plug one of the points given and your slope into point slope form. This form is Y-Y1=m(X-X1). Then you to get your final answer you want to get Y to be by itself.

Your problem:
5-(-1)/1-(-1)
5+1/1+1
=6/2 =3
m=3

Y-(-1)=3(X-(-1))
Y+1=3(X+1)
Y+1=3X+3
Y=3X+2
