Question 741026
So you are going to plug in you x and y into your equations.
4 is x
2 is y

For the equation--- y= -5x+22
2= -5(4)+22 That means two equals negative five time by four plus twenty two
2=  -20 + 22 That means two equals negative twenty plus twenty two
2=2 That means two equals two which is correct

Next Equation  ------ y= 8x - 30 
2 = 8(4) - 30 That means two equals eight times four minus thirty
2 =  32 - 30  That means two minus thirty two minus thirty
2 = 2 That means two is equal to two which is correct

It is always ( x, y) in all equations just plug in the numbers
Hope i helped
