Question 68389
find the slope of a line that is perpendicular to the following lines.
y=-1/5x-7

Solution:

Slope - intercept form of a linear equation is written as y = mx +b, where m = slope and b = y-intercept.

From the given equation {{{y = (-1/5)x - 7}}}, m = -1/5.
Since the slope of the line we are looking for is perpendicular to the line line form by {{{y = (-1/5)x - 7}}}. 

Answer: {{{m = 5}}} 

Note: If the line is perpendicular to the other line, slope is the negative reciprocal of the other slope.
