Question

I hoped the graph would be a line with x-intercept 1 and y-intercept 1. The equation of such a line is....

A) x - y = 1
B) x + y = 1
C) x + y = -1
D) y = x + 1

Answer 1

x-intercept means y equals to 0
y-intercept means x equals to 0

If you plug in (0, 1) and (1, 0), you will notice that only x + y = 1 will work for both points

Your answer is B) x + y = 1
