Answer:
Alexander is incorrect because the expressions are not equivalent.
Step-by-step explanation:
If the expression is evaluated for any value of x, y; the result will not be same.
For instance, let assume x = 1 and y = 2
3x + 4y = 3 + 4 = 7
(3)(4) + xy = (3)(4) + (1 * 2) = 12 + 2 = 14
So, the expressions are not the same and Alexander is incorrect.

Answer:
x-y=5
Step-by-step explanation:
If a line has a slope of 1, its function can be write as x-y=c
insert point (7,2),t then we can find out the constant c=5, so the equation of this line is x-y=5
Ok so Dianne pays $28 to get into the fair, she pays $2 for each ride she ride's so I think the equation would be 28+2x= the amount of money she paid
