They are giving me the graph of y=-2x+4 and telling me to use that graph to solve the equation 4=-2x+4.

Revise back this equation:-

y = mx + c

From this equation (x,y) is the point in your graph,
m is the slope either negative or positive,
and the c is the y-axis crossing.

You are given this equation:-

y = -2x + 4 ……………………………(1)

So, from here:-

Slope = -2
y-axis crossing = 4

You are request to solve this equation:-

4 = -2x + 4 ……………………………(2)

The point you are looking for is (x,4)

So just find the value of x from the (2):-

Therefore,
4 = -2x + 4
x = (4 – 4) / (-2)
x = 0

So the point that you are looking for is (0,4)

assuming you will give me the BEST ANSWER i will tell you. -2 is the slope and the 4 is the Y axis in the first equation. Im not really sure what your question is but if it asks for one of the 2 they are right. u would solve the second one by adding +2 to the -2x so that it would be 4x on the right side and add 2 to the left side then it would look like 6=4x the you would divide by 4 so the left side would equl X and then divide the 6 by 4 which is 1.5 so X=1.5

If 4=-2x+4, then 0=-2x, x=0, no matter what Y is. The two formulae are independent. You don't need a graph, just solve the algebra.

well, comparing y = -2x +4 and 4 = -2x + 4, we can see that y = 4
so, just look on the graph and when the y-value (vertical axis) is equal to 4, it will give you the x-value (horizontal axis)

Draw the graqh. Then fin the point where y = 4.
