Question

Find the slope of every line that is perpendicular to the graph of the equation. y-5x=7

Answer 1

First we need to find the slope of the equation given by putting the equation in y = mx + b form, where m is your slope. Can you do that ?

Answer 2

first convert it in standard form
y=mx+c
y+5x=7
move 5x on other side
then coefficient of x with its sign = value of m
for two lines to be perpendicular
product of their slope = -1
m* slope of perpendicular line = -1
slope of perpendicular line= -1/m
