Question

Urgent: What is an equation of the line perpendicular to y=-x-2 and through (-2,4)?

Answer 1

Point slope form- y-4=(x+2)
Slope intercept- y=x+6

Answer 2

Perpendicular line means the gradient will be negative reciprocal. The gradient of the line that is given is -1.

Therefore the gradient of the perpendicular line is -1 / -1 = 1

Now we know the equation is y=x+c

We want to find out what c is.

To do this, we substitute in the coordinates given:

4 = 1(-2) + c

4 = -2 + c

C= 6

Therefore the perpendicular line equation is:

y = x + 6
