Question

What is the equation of the line that passes through (2,1) and is perpendicular to the graph of y= -x + 2?

1) y= x-1
2) y= x+1
3) y= -x+3
4) y= -x+2

Answer 1

how do slopes of perpendicular lines compare?

Answer 2

opposite?

Answer 3

opposite of the reciprocal

Answer 4

so which 2 of these has the opposite of the reciprocal of the slope of the line given?

Answer 5

the slope of the line given is -1 so the opposite of the reciprocal of -1 is 1

Answer 6

so u want a line with slope 1. and when u plug in 2 for x y becomes 1

Answer 7

so its A
y=x-1

Answer 8

thank you
