Answer:
do you have any answer choices
<u>Part a</u>
The domain is the set of x-values, which is 
<u>Part b</u>
The range is the set of y-values, which is ![(-\infty, -2]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%20-2%5D)
<u>Part c</u>
The x-intercepts is when y=0, which there are none of.
<u>Part d</u>
The y-intercept is when x=0, which is at (0, -2).
<span>7x-4y=-7
5x+y=22
multiply 4 on the 2nd equation
</span>20x+ 4y=88
now you have
7x -4y = -7
20x + 4y = 88
--------------------add
27x = 81
x = 3
7x-4y=-7
7(3)-4y=-7
-4y = -28
y = 7
answer (3, 7) is the solution
