What is the value of y in this system of equations?
-6x + 2y= -18
-3x-2y=54

Line up the equations and add them up, adding the x's together then y's (which should cancel out) then the totals.

Then the equation should equal -9x=36 and when tou solve x= -4.

Plug -4 in for x in one of the equations, I chose the second one, and solve.

y = -21

Hope this helps! :)

B.the point lies directly on the regression
