Question

Write an equation in slope-interept for, for the lnie that satisfies each set of conditions.

8. passes through (-2, 1), perpendicular to the line y=4x - 11

Help! not sure where to even begin.
if perpendicular, the the new slope must be -1/4 and the equation must be

y = (-1/4)x + b
sub in the point (-2,1)
1 = (-1/4)(-2) + b
b = 1/2

equation: y = (-1/4)x + 1/2
