Question

A line goes through the two points (3,7) and (-2,-8). Louis

thinks that the equation of the line is y = 3x - 2.
Do you agree? Explain your answer.

Answer 1

-8 - 7/ -2 - 3 = -15/-5 = 3
3 it’s the slope

7=3(3) +b
7=9 +b
-9. -9
-2=b


Y=3x-2


Yes I’m agree, because if you find the slope with the formula y2-y1/x2-x1 you can find the slope and if you use the formula y=Mx+b you can find the y- intercept.
