Question
The line passing through $(-1, y)$ and $(1,0)$ is perpendicular to the line joining $(2,3)$ and $(-2,1) .$ Find $y$
Step 1
The slope of a line given two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by the formula $\frac{y_2 - y_1}{x_2 - x_1}$. So, the slope of the line is $\frac{1 - 3}{-2 - 2} = \frac{-2}{-4} = \frac{1}{2}$. Show more…
