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

dusya [7]

Answer:

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 .
