What are the signs of the slope and the y-intercept in the line y = 13x - 6?
Answer and explanation
Correct answer: Slope is positive and y-intercept is negative
In the standard form y = mx + c, the coefficient of x gives the slope and the constant c gives the y-intercept. Comparing y = 13x - 6 with this form gives m = 13, which is positive, and c = -6, which is negative. Thus option A is correct. The other choices either reverse one sign or incorrectly claim that both signs are alike.
