Question

Find the slope of a line perpendicular to each given line.

y= -2x -2

Answer 1

Explanation:

solution

Equation of line,

y=-2x-2

2x+y=2 - - - - - - -1

Now,

slope of line,

m= -x coefficient/ y coefficient

= -2/1

= -2

Slope of required line which is perpendicular to the line

m.m = -1

-2.m = -1

m = -1/-2

m =1/2

Answer 2

Using the slope-intercept form, the slope is −2 .
