Question

Find the slope of a line parallel to the line that crosses (2,4) and the y-intercept is (0,−1).M = ?

Answer 1

We have to find the slope of a line that is parallel to another line that crosses (2, 4) and has y-intercept (0, -1).

All parallel lines have the same slope, so we can just calculate the slope of the line that crosses through (2,4) and (0,-1).

We then can calculate the slope as:

$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{-1-4}{0-2}=\frac{-5}{-2}=2.5 \end{gathered}$

Answer: the slope is m = 2.5 or 5/2.
