Question

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

Answer 1

d

Explanation:

We are given that one equation for function A and the graph for function B

Function A

Function B : The graph of line going through ordered pair (-1,-5) and (2,1) and (3,3)

The equation of a line passing through two points and is given by

The equation of function B passing through the points (-1,-5) and (2,1)

Where

The equation of function B passing through the points (-1,-5) and (2,1)

The equation of function B passing through the points (-1,-5) and (2,1)

The equation of function B passing through the points (-1,-5) and (2,1)

The equation of function B passing through the points (-1,-5) and (2,1)

The equation of function B passing through the points (-1,-5) and (2,1) is given by

Therefore, slope of function B=2

By comparing with the equation of line

Slope of function A= -2

Therefore, slope of function B=- Slope of function A.

Hence, option d is true.

Answer 2

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