D=$1000 and 3d =$500w

2

Step-by-step explanation:

First let's find two clear points on this line. These points are shown by two black dots on the line.

Their coordinates are:

(0, -3) and (2, 1)

Now we want to use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in the coordinates we just found.

(1 - (-3)) / (2 - 0)

Simplify the parentheses.

= (1 + 3) / (2)

= (4) / (2)

Simplify the fraction.

4/2

= 2

This is your slope.

Hope this helps!
