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

-0.5

Step-by-step 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.

Step-by-step 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.
