Question

11.3 following: Find the slope of a line parallel to the line through the points (d) (10, 7) and (-4,7)

Answer 1

The slopes of parallel line are alway equal

So, the slope of line whcih passes through (10, 7) and (-4,7)​ is equal to its parallel line

Expression for Slope

$\begin{gathered} \text{ Slope=}\frac{y_2-y_1}{x_2-x_1} \\ \text{ Slope=}\frac{7-7}{-4-10} \\ \text{ Slope =}\frac{0}{-14} \\ \text{ Slope = Not defined} \end{gathered}$

Slope is not defined

So, the line which is parallel to given line's slope is not defined

Answer : not defines
