Question

is (-2, 6) a solution to this system of equations?
y = x + 8
y = -6x - 9
yes
no

Explanation:

Step1: Substitute x and y values into first - equation

Substitute \(x=-2\) and \(y = 6\) into \(y=x + 8\).
\(6=-2 + 8\)
\(6=6\) (True)

Step2: Substitute x and y values into second - equation

Substitute \(x=-2\) and \(y = 6\) into \(y=-6x-9\).
\(6=-6\times(-2)-9\)
\(6 = 12-9\)
\(6=3\) (False)

Answer:

no
