Question

is (-7, 9) a solution to this system of equations?
y = -10x - 5
y = -x + 2
yes
no

Explanation:

Step1: Substitute x and y values in first equation

Substitute \(x = - 7\) and \(y = 9\) into \(y=-10x - 5\).
\[9=-10\times(-7)-5\]
\[9 = 70 - 5\]
\[9
eq65\]
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
