Question

Is y−4=3(x+1) an equation of a line through (-2, 1)? Explain.

Answer 1

Yes

Explanation:

(1)-4=3((-2)+1)

-3=3(-1)

-3=-3

The answer is yes because if you substitute x and y for -2 and 1 you can simplify the equation. Then you get the answer -3=-3 which means that the equation is equal.
