Question

21) Write the equation for the line through two given points.

Passing through (0, -1) and (2, 3)

Answer 1

Point Slope: (y + 1) = 2x

Slope Intercept: y = 2x - 1

Explanation:

I'll do it in two forms.

Slope = (3 + 1) / (2 - 0) = 2

Point - Slope: (y + 1) = 2x

Slope Intercept: y = 2x + b

-1 = b

y = 2x - 1
