Perpendicular lines have slopes that are negative reciprocals
so if m1 = -3
the perpendicular line has a slope of 1/3
Answer:
commutative property of addition
Step-by-step explanation:
C) It doesn’t satisfy either the top or bottom equations.
When we plug them into the top equation:

Simplify:

Because the statement of -23 = -15 is wrong, the solution pair is wrong for the top equation.
When we plug them into the bottom equation:

Simplify:

9 = -8 is not a valid statement, so the pair doesn't satisfy both of the equations.
Yeah uh show us a photo of the equation
