Answer:

Slope of Function A = 2 x Slope of Function B

Step-by-step explanation:

Function A has equation: [tex]f(x)=6x-1[/tex].

The slope of this function is the coefficient of x which is [tex]m=6[/tex].

Function B goes through:(1,4), (-1,-2),(-2,-5).

Use the slope formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope of this line.

Let us substitute the first two points.

[tex]m=\frac{-2-4}{-1--1}[/tex].

[tex]m=\frac{-6}{-2}[/tex].

[tex]m=3[/tex].

We know that: 6=2(3).

Hence, Slope of Function A = 2 x Slope of Function B
