Question

5. Use the points (4, 10.5) and (8,5.7) to estimate the slope of the line of best fit. Answer choices: 0 83 0.83 -1.2 1.2 1 7​

Answer 1

Answer:

Slope of the line is -1.2

Option B is correct option.

Step-by-step explanation:

We need to find slope of the line with given points (4, 10.5) and (8,5.7)

The formula used to calculate slope is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

The points given are: (4, 10.5) and (8,5.7)

We have $x_1=4,y_1= 10.5x_2=8,y_2=5.7$

Putting values and finding slope

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{5.7-10.5}{8-4}\\Slope=\frac{-4.8}{4}\\Slope=-1.2$

So, Slope of the line is -1.2

Option B is correct option.
