Question

can you please solve this practice problem for me I need assistance. for question 3 the answer choice is 1. Start at the given point and go up 2 over 12.Start at the point of the origin and go up 2 over 13. Start at the given point and go down 2 over 1 4. Start at the -2 and go down 2 over 1

Answer 1

Part 1

To calculate the slope of Graph D, we pick any two points on line D.

The points we have chosen are (8,0) and (7,4).

`\begin{gathered} \text{Slope}=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}} \\ =(4-0)/(7-8) \\ =(4)/(-1) \\ =-4 \end{gathered}`

The slope of the line in Graph D is -4.

Part 2

The line in Graph E is a horizontal line.

The slope of any horizontal line is 0.

The graph could represent the speed of a car in park (i.e not moving at all).

Part 3

If the indicated point is (0,0).

For the line to have a slope of -2, the other point will be:

`(1,-2)`

The drawn graph is attached below:

This means that we start at the given point, and go down 2 over 1.

The correct choice is 3.
