Write an equation in slope-intecept form for the line that passes through (8,-1) and is perpendicular to y=-4x-7

Hello:

the equation is : y = ax+b

the slope is a : a * (-4) = - 1 ... (perpendicular to a line with a slope of 4)

a = 1/4

: y = (1/4) x + b

the line that passes through (8, - 1) : - 1 = (1/4) (8) + b

b = - 3

the equation is : y = (1/4) x-3
