Rectangle MNOP with vertices M(-7, 1),
N(4, 1), 0(4, 4), and P(-7,4) in the line
y = -x

Where are the functions?

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
