Question

Part 1: Write the equation of the line that passes through the points (–1, –4) and (2, 5).

Part 2: Using complete sentences, explain whether or not it matters which point is used in the final answer. Also explain why you chose the point you did.

Answer 1

im guesing my using y=mx+b?

Answer 2

(y-y1) / (x-x1) = (y2-y1) / (x2-x1)
(y-(-4)) / (x-(-1)) = (5-(-4)) / (2-(-4))
(y+4) / (x+1) = (5+4) / (2+4)
(y+4) / (x+1) = 9 / 6
(y+4) / (x+1) = 2/3
y+4 = 2(x+1)/3
3(y+4) = 2(x+1)
3y+12 = 2x+2
2x-3y-10=0
or 2x-3y = 10
