Linerar Equations in 2 Variables

Complete the ordered pair for the equation y=-10x+18 I have one of the ordered numbers given to me by my instructor, I have to come up with the first one, this is excactly how he gave it to me, but I really don't understand this...Can someone please help me understand it better? (_, 78)
_ is the x value, 78 is the y value.
Substitute 78 for y and solve the equation given for x. The answer I obtained is -6 but check my work.
