Hey there! :)
Answer:
(2, -2)
Step-by-step explanation:
-2x + y = -6
4x + 3y = 2
We can begin by setting the first equation equal to y:
-2x + y = -6
Add 2x to both sides:
y = 2x - 6
Plug this equation for y into the second equation:
4x + 3(2x - 6) = 2
Distribute:
4x + 6x - 18 = 2
Combine like terms:
10x = 20
x = 2
Plug the value of 'x' into an equation to solve for 'y':
-2(2) + y = -6
-4 + y = -6
y = -2
Therefore, the solution is (2, -2)

Answer:
A and B only
Step-by-step explanation:
The table has x=10 that maps on to y=5 and y=-5.
This disqualifies the table for being a function.
The ordered pairs has no x-value repeating.
The graph of y=x² +10 is a vertical parabola that passes the vertical line test, hence it is also a function.
For a relation to be a function, no x-value must repeat; this means its graph must pass the vertical line test
