Question

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

Answer 1

do you know the point slope formula?

Answer 2

y-y1 = m( - x1)

sooo slope (or m) = change in y divided by change in x
5--4/2--1 = 9/3 = 3
y-y1 = 3(x -x1)
y-2 = 3(x+1)

Answer 3

OR
y = 3x +5

Answer 4

ok so you subtracted ?

Answer 5

yeah, and distributed the 3

Answer 6

does it matter what p[oint i use to graph?
