What is the equation of the line that is perpendicular to the line y=}x+10 and passes through the point (15,-5)? -x+
V
O y=xx-20
O y=-3x +20
Ov=x-20
O y=-x+20

thats one

step-by-step explanation:

first 15 divide by 2 = 7.5

100 divided by 7.5 is 13.

15 / 2 = 7.5

100 / 7.5 = 13.

set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.
