is (-7, 9) a solution to this system of equations?\ny = -10x - 5\ny = -x + 2\nyes\nno

Explanation:

Step1: Substitute x and y values in first equation

Substitute (x = - 7) and (y = 9) into (y=-10x - 5). [9=-10\times(-7)-5] [9 = 70 - 5] [9\neq65] Since the left - hand side is not equal to the right - hand side when substituting into the first equation, there is no need to check the second equation. So ((-7,9)) is not a solution to the system of equations.

Answer:

no
