Point-slope form : y-y₁=m(x-x₁)
Perpendicular to the given line, and passes through (-4, -3)
Given line slope : -4
How we found slope : I found 2 exact points, and found the slope by doing the slope formula (y₂-y₁/x₂-x₁)
m = slope
However, when a line is perpendicular, we must find the negative reciprocal of our slope.
Slope₁ = -4
Slope ₂ = 1/4
Simply plug everything in.
y - y₁ = m(x - x₁)
y + 3 = 1/4(x +4)
What is the equation, in point-slope form, of the line that is perpendicular to the given line and passes through the point (−4, −3)?

The slope was not given, (there was no "given line").
Veronica's answer is partially correct, except there was no way of finding the slope.

I suspect the student tried to copy and paste the original equation.
