Question 549440
You did not provide directions but I'll assume that you want to know if the point given lies on the graph of the linear equation.


Replace x with 8 and y with -2.


If after doing the math the answer is the same on BOTH sides of the equation, then we know for sure that the point is on the line.


4(8) - 2(-2) = 9


32 + 4 = 9


36 DOES NOT equal 9.


So, the point (8, -2) does not lie on the graph of the linear equation given.


If this is not what you want, then provide directions.
