You can put this solution on YOUR website!
a.) Choose an x value then compute the y value.
I'll do one, you do the other two.
Let x=0,
y=2x-5
y=2%280%29-5
y=0-5
y=-5
(0,-5)
.
.
.
.
b) Again using my first example, choose any y other than y=-5 and x=0.
(0,12) will fail the test
12=2%280%29-5
12=0-5
12=-5
False, so (0,12) is not an ordered pair for that wequation.
