Write an equation in slope-intercept form for the line perpendicular to y=−4x+1 that passes through the point (−7,1).

slope intercept form is: y= mx +c

Step-by-step explanation:

Given : linear equation y = -4x + 1, the slope is m = -4

[you can read the slope m ,  from the equation]

rule for perpendicular slope: m1 x m2 = -1

Let the slope in the original equation equal m1, i.e. m1 = -4

therefore, -4 x m2 = -1

m2 = -1/-4

slope of perpendicular line = 1/4

so, y = 1/4 x + 1

its 8
