Question

Plz help me it's due In 20 minutes!!!!! Function A f(x) = - 2x - 1 Function B 2 - 2 -1 -1 2 -3 Which equation best compares the slopes of the two functions? (1 point) Slope of Function B = 2 x Slope of Function A. Slope of Function A = Slepe of Function B Slope of Function A = 2 x Slope of Function B Slope of Function 3 = - Slope of Function A​

Answer 1

D. slope of function B = - slope of Function A

Explanation:

Slope-intercept form: f(x) = mx + b

Function A: f(x) = -2x + 1

Function A is written in slope-intercept form, where m is the slope. This means that the slope of Function A is -2.

To compare the slopes of the 2 functions, we have to find the slope of function B. the slope is also known as the rise over run of a line. To find the slope using the graph, look and see how much the line goes up by every time it moves over 1. The line moves from point (0, -3) to point (1, -1). Then it goes from point (1, -1) to point (2, 1). Every time the line moved over one point on the x-axis, it increased by 2 points on the y-axis. This means that the slope of Function B is 2.

Now that we know the slopes of both functions, let's compare them:

Function A slope = -2

Function B slope = 2

If we equal the slopes to each other, we get:

2 = -2

This can also be represented as:

slope of function B = - slope of Function A

Answer choice D is the correct option.

Hope this helps :)
