The line (y=mx-13) passes through ((-5,12)). What is its slope?

Answer and explanation

Correct answer: \(-5\)

Substitute the point \((-5,12)\) into \(y=mx-13\): \(12=m(-5)-13\). Hence, \(25=-5m\), so \(m=-5\). Therefore, the correct option is \(\mathbf{-5}\). If \(m=5\), the equation gives \(y=-38\) when \(x=-5\), so it cannot pass through the given point. Exam tip: To find an unknown slope parameter, substitute the coordinates of the given point into the line equation.
