What are the slope and (y)-intercept of the line (5y=-10x+25)?
Answer and explanation
Correct answer: Slope \,(-2) and \(y\)-intercept \,5
Write the line in slope-intercept form \(y=mx+c\) by dividing both sides by 5: \(y=-2x+5\). The coefficient of \(x\), \(m=-2\), is the slope, and the constant term, \(c=5\), is the \(y\)-intercept. Option A incorrectly uses the coefficients before dividing by 5. Exam tip: first rewrite the equation as \(y=mx+c\), then identify \(m\) and \(c\).
