If (m>0) and (c<0) in (y=mx+c), which statement is correct?
Answer and explanation
Correct answer: The slope is positive and the y-intercept is negative
In the line y=mx+c, m is the slope and c is the y-intercept. Since m>0, the slope is positive; since c<0, the line cuts the y-axis below the origin, so the y-intercept is negative. Option B reverses both signs. Exam tip: In y=mx+c, identify m directly as the slope and c as the y-intercept.
