If (m<0) and (c<0) in (y=mx+c), which statement is correct?
Answer and explanation
Correct answer: The slope is negative and the y-intercept is negative
In the line equation y=mx+c, m represents the slope and c represents the y-intercept. Here m<0, so the slope is negative, and c<0, so the y-intercept is also negative. Therefore, option B is correct. In option A, the y-intercept is negative, but the slope is incorrectly stated as positive. Exam tip: In y=mx+c, the sign of m gives the slope’s sign and the sign of c gives the y-intercept’s sign.
