Question

What is the equation in point-slope form of the line passing through (−2, 0) and (2, 8)?

y = 2(x + 2)

y = 2(x − 2)

y = −2(x − 2)

y = −2(x + 2)

Answer 1

point slope form =y-y1=m(x-x1)

Answer 2

m=slope

Answer 3

First find slope using slope
\[a=\frac{y_2-y_1}{x_2-x_1}\]
then the equation of a line with slope "a" through point P1 is
\[y-y_1=a(x-x_1)\]
simplify as required.
