Answer:
Step-by-step explanation:
Use the "vertical line test." Draw a vertical line through each graph. If the line intersects the graph in more than one place, the graph does NOT represent a function. Only the graph in the upper, right-hand corner represents a function, as a vertical line intersects this graph in only one place.
40 + x
That's the expression you're looking for.
Which value of x and y when plugged into the equation will create the same value on both sides?
The best way to do this is by trial and error.
Let's try x = 3 and y = 14.
y = 2x + 8
14 = 2(3) + 8
14 = 6 + 8
14 = 14
We got the same answer on both sides.
