I presume you meant to write y=-%283%2F4%29x%2B2
Based on those assumptions, let's test the given ordered pairs beginning with answer D:

D: red%281%2F4%3C%3E-%283%2F4%29%2A3+%2B+2+=-%289%2F4%29%2B2=-%281%2F4%29%29

C: red%285%3C%3E-%283%2F4%29%2A%28-2%29%2B2=6%2F4%2B2=14%2F4%29

B: red%28-%281%2F4%29%3C%3E-%283%2F4%29%2A1%2B2=-%283%2F4%29%2B2=5%2F4%29

A: green%2811%2F4=-%283%2F4%29%28-1%29%2B2=3%2F4%2B2=11%2F4%29 TA DA!!

On the other hand, if your equation is actually y=-%283%2F4%29%2B2 as you wrote, then y=5%2F4 for all values of x and since none of the given answers has a y-coordinate of 5%2F4, none of the answers would be correct.
