Through (-20,4) and <br> perpendicular to y=x+5
WITCHER [35]
<h3>Answer:  y = -x - 16</h3>

========================================================

Explanation:

The given equation is the same as y = 1x+5 which is in y = mx+b form.

  • m = slope = 1
  • b = y intercept = 5

Anything perpendicular to this will have a slope of -1, which is the negative reciprocal of the original slope.

We'll use this perpendicular slope along with (x,y) = (-20,4) to find the equation of the perpendicular line.

y = mx+b

y = -1x+b ... plug in the perpendicular slope

4 = -1*(-20)+b ... plug in the x,y coordinates

4 = 20+b

4-20 = b

-16 = b

b = -16

Therefore, we go from y = mx+b to y = -x-16

A line passes through the points ( -5, 1) and ( 2, -9) what is the slope of the line?
Reika [66]

Answer:

slope=(y2-y1)/(x2-x1)

where (x1, y1)=(-5,1)

(X2,y2)=(2,-9)

slope=(-9-1)/(2+7)=-10/9
