Which of the following lines has a negative slope and a positive y-intercept?

Answer and explanation

Correct answer: \(y=-2x+5\)

In \(y=mx+c\), \(m\) is the slope and \(c\) is the y-intercept. In option A, \(m=-2\) is negative while \(c=5\) is positive. Option C has a negative slope too, but its intercept is negative. Exam tip: check the signs of the x-coefficient and constant separately.
