Question

What is the equation in point-slope form of the line passing through (2, 5) and (–1, 8)?

y + 5 = 1(x + 2)

y + 8 = –1(x – 1)

y – 5 = –1(x – 2)

y – 8 = 1(x – 2)

Answer 1

the 3rd equation.

Answer 2

huh.. how do you know?

Answer 3

correct

Answer 4

you can put x from the first of (x, y) on the equation, so if the solution will be y, the equation is true.
