Question

On the graph below, draw two slope triangles that can be used to find the slope of the line. Use the triangles to determine the slope and write the slope of the line. Length of shadow (inches) y4 150 125 100 75 50 25 0 Slope (72, 48) (43, 29) 25 (51,34) (171, 114) 50 75 100 125 150 175 x Height (inches) E​

Answer 1

The calculated slope of the line using the triangle is -1/2

How to determine the slope of the line

From the question, we have the following parameters that can be used in our computation:

The triangles

The slope of the line using the triangle can be calculated using

Slope = Rise/Run

Where, we have

Rise = 2

Run = -4

Substitute the known values into the equation

Slope = 2/-4

Evaluate

Slope = -1/2

Hence, the value of the slope is -1/2
