he equation below represents function a and the graph represents function b: function a f(x) = – 2x 1 function b graph of line going through ordered pairs negative 1, negative 5 and 2, 1 and 3, 3 which equation best compares the slopes of the two functions? slope of function b = 2 x slope of function a. slope of function a = slope of function b slope of function a = 2 x slope of function b slope of function b = – slope of function a

slope of function a = -2
slope of function b = (1 + 5)/(2 + 1) = 6/3 = 2
slope of function b = - slope of function a.

Answer:

Option D.

Step-by-step explanation:

The slope intercept form of a line is

Function a: [tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

The given function is

[tex]f(x)=-2x+1[/tex]

The slope of the line is -2 and y-intercept is 1.

If a linear function passes through two points, then the slope of the line is

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

It is given that the graph of function b passes through the points (2,1) and (3,3).

[tex]m=\frac{3-1}{3-2}[/tex]

[tex]m=\frac{2}{1}[/tex]

[tex]m=2[/tex]

The slope of function b is 2.

Slope of function b = – Slope of function a

Therefore, the correct option is D.
