Question 444634: Though (0,-1) and perpendicular to 4x-2y=3. Solve.
Answer by oberobic(2304) (Show Source): You can put this solution on YOUR website!
Get the equation into slope-intercept form.
4x -2y = 3
-2y = -4x +3
y = 2x + 3/2
.
A perpendicular line will have the slope -1/2.
y = -1/2x + b
.
The challenging part is you want this line to go through the point (0,-1).
That means "when x = 0, y = -1"
.
Substitute what you know.
-1 = -1/2(0) + b
-1 = b
.
So the equation is:
y = -1/2x -1
.
