Question

Consider the function f(x) = -2x - 8. The slope is:
a) 2
b) -2
c) 8
d) -8

Answer 1

b) -2

Step-by-step explanation:

By following the slope-intercept formula (in this case, f(x) and y are the same value), which is:

y = mx + b

m is the slope, which will always be the number next to x. If it has no number, the slope can be assumed to be 1.

The number next to x in this case is -2.

Answer 2

The slope of the function f(x) = -2x - 8 is -2.

Step-by-step explanation:

The slope of a linear function can be found by looking at the coefficient of x. In the function f(x) = -2x - 8, the coefficient of x is -2. Therefore, the slope of the function is -2.

The correct answer is b) -2.
