Write the following statement as a mathematical expression. State whether the expression is a linear or nonlinear expression in x. Seven subtracted from five times a number, and then the difference added to nine times a number.

5x-7+9x

I don't actually  know if this is correct 100% but I'm pretty sure it is a linear expression.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
