: Please help! My intructions are: Graph the points and draw a line through them. Write an equation in slope-intercept form of the line that passes through the points.
I understand my instructions and I understand the graphing part of it but I can't seem to get the right answer. All the book gives me are two plot points; (-1, -2), (2, 6).
I've done the beging to find the slope, m. 6+2 divided by 2+1 and got . I've tried it many time and keep getting different answers for "x" and "y" and can't get "b". The answer in the back of my textbook is .
Once again please help.This question is from textbook Algebra 1

All the book gives me are two plot points; (-1, -2), (2, 6).
I've done the beging to find the slope, m. 6+2 divided by 2+1 and got8/3.
I've tried it many time and keep getting different answers for "x" and "y" and can't get "b".
---------------
y=mx+b
You are given x=2, y=6 and you figured out m=8/3
So, 6=(8/3)*2+b
b=(18/3)-(8/3)
b=10/3
EQUATION:
y=(8/3)x+(10/3)
-------------
What the "book" gives is wrong if the points are as
you posted them.
