Question

Given the graph of a line y=−x. Write an equation of a line which is perpendicular and goes through the point (8,2).

Answer 1

Answer:

y = x - 6

Step-by-step explanation:

The slope of y = -x is -1, so the slope of any line perpendicular to y = -x is +1.  Thus,

y = mx + b becomes 2 = 1(8) + b, so that b = -6.

The desired equation is y = x - 6.

Check:  Does (8,2) lie on this line?  Is 2 = 8 - 6 true?  YES.

Answer 2

Answer:

Y=X-6
