Question

The description below represents Function A and the table represents Function B: Function A The function is 2 more than 5 times x. Function B x y −1 2 0 5 1 8 Which statement is correct about the slope and intercept of the two functions?

Answer 1

Their slopes are equal but y-intercepts are not equal.

Explanation:

Its simple arithmatics

Answer 2

The slope of Function A is greater than the slope of function B while the y-intercept of Function B is greater than the y-intercept of function A.

Explanation:

Function A is f(x) = 5x + 2

The slope is 5 and the y-intercept is (0, 2).

Function B. The slope is (5-2) / (0- -1) = 3.

also (8-5) / (1 - 0) = 3

The slope is 3.

The y-intercept is at (0, 5) because one point on the graph is (0, 5).
