Question 1 Report

Find the equation of the line through the points (-2, 1) and (- $\frac{1}{2}$ , 4)

y = 2x - 3

y = 2x + 5

y = 3x - 2

y = 2x + 1

Answer Details

$\frac{y - y_{1}}{x + x_{1}}$ = $\frac{y_{2} - y_{1}}{x - x_{1}}$
$\frac{y - 1}{x + 2}$ = $\frac{4 - 1}{- \frac{1}{2} + 2}$
= $\frac{y - 1}{x + 2}$ = $\frac{3}{\frac{3}{2}}$
y = 2x + 5
