What is the slope of the equation (y+5=2x)?
Answer and explanation
Correct answer: 2
Write the equation in slope-intercept form: \(y+5=2x\), so \(y=2x-5\). In the form \(y=mx+c\), the coefficient of \(x\), namely \(m\), is the slope. Therefore, the slope is \(2\). Here, \(-5\) is the y-intercept, not the slope. Exam tip: isolate \(y\) first and then identify the coefficient of \(x\).
