Practice problem
Find the equation of the line through (4,−1)(4, -1)(4,−1), perpendicular to the line: y=4x−2y = 4x - 2y=4x−2
y=14x−3y = \frac{1}{4}x - 3y=41x−3
y=14x+2y = \frac{1}{4}x + 2y=41x+2
y=−14x−2y = \frac{-1}{4}x - 2y=4−1x−2
y=−14xy = \frac{-1}{4}xy=4−1x
Type a concept, like “slope” or “photosynthesis”.
