Answer 1

On the image you linked (I'm assuming it's one of your answer choices) is it true that

x+y=5

for every point on that line? (The intercepts are two easy points to check.)

Think about what the SLOPE and Y-INTERCEPT will be for the line x+y=5. It's almost in slope-intercept form already, so should be easy to see. Just solve for y=mx+b, and then:

m=?
b=?

Then look for a choice with that slope and intercept.
