Question

What is the equation of the line that passes through the point (2, 3) and is perpendicular to the line y = -x - 3?

y = -x - 1
y = -x + 5
y = x + 1
y = x + 5

Answer 1

the slope of a line perpendicular to y = mx + c has slope -1/m
so in your case the slope is 1/-1
using this and plugging in value x=2 and y=3 into the above to see if they satisfy the equation will give you the answer

Answer 2

sorry - second line typo : slope is -1 / -1
