Question

Given f(x) = –7x + 9 and h(x) = –5(–7x + 9), what are the slope and y-intercept of the graph of function h? slope = y-intercept =

Answer 1

the slope, m, is 35 and the y-intercept, b, is -45

Explanation:

Here we don't need to use f(x) at all.

h(x) = -5(-7x + 9) becomes h(x) = 35x - 45. From this last result we see that the slope, m, is 35 and the y-intercept, b, is -45.
