Question

What is the slope of the line that is perpendicular to the line whose equation is 2x + y = 4.
​

Answer 1

-0.5

Explanation:

Given that the slope is 2, the opposite of that is -0.5. Take the fractions and flip them. 2 is 2/1. If you reverse 2/1, you get -1/2.

Answer 2

Explanation:

Given equation is 2x+y=4 .so slope(m1) = - coefficient of x / coefficient of y= -2/1=-2

• we have slope of the line perpendicular to the other line is m1*m2=-1\
• then slope of the line perpendicular to the line 2x+y=4 is -2*m2=-1\
• then -2/-1=m2 therefore m2 =2 .
