It's the first one. y can equal x as long as y doesn't equal x multiple times. We also know the last two are wrong because they're saying the same thing. A linear function is a straight line.
Multiplying ,you get 18x^2+21x-24x-28. You simplify to get:
18x^2-3x-28.
Answer:
(1/2)% = 0.5% =0.5/100 = 0.005
=> Option E is correct.
Hope this helps!

3x - y = 9
y = -2x + 11
3x - (-2x + 11) = 9
3x + 2x - 11 = 9
3x + 2x = 9 + 11
5x = 20
x = 20/5
x = 4
y = -2x + 11
y = -2(4) + 11
y = -8 + 11
y = 3
solution (where the lines intersect) is (4,3)
