Question 1152395
Write am equation of the line passing through the point (4,-1) and perpendicular to the line y=2x-5
------------------
Step 1, find the slope of the line y = 2x - 5
Step 2, lines perpendicular have a slope that's the negative inverse of the line.
--------------
Step 3, use
y - y1 = m*(x - x1) where m is the slope of the perpendicular lines, and (x1,y1) is (4,-1).
===========================
I don't need the practice.
You do.
