line given is
4x − y = 4
rearranged that is
y = 4 x - 4 so slope = 4
new slope = -1/old slope
so
m = -1/4
y = -x/4 + b
to find b put the point in
2 = -(1/4)(-7) + b
solve for b
Write the equation of the line that satisfies the given conditions. Express the final equation in standard form.
Contains the point (-7, 2) and is perpendicular to the line 4x − y = 4
