Find the slope of the line through the given points.(-4,7) and (-1,-3)Is the slope increasing or decreasing?
galina1969 [7]

• The following formula can be used to find the slope of a line:

m=\frac{y_2-y_1}{x_2-x_1}

These points are on the line:

(x_1,y_1);(x_2,y_2)

Given the following points:

\mleft(-4,7\mright);(-1,-3)

Then, you can set up that:

\begin{gathered} y_2=-3_{} \\ y_1=7 \\ x_2=-1 \\ x_1=-4 \end{gathered}

Therefore, substituting values into the formula and evaluating, you get:

\begin{gathered} m=\frac{-3-7}{-1-(-4)} \\  \\ m=\frac{-10}{-1+4} \\  \\ m=-\frac{10}{3} \end{gathered}

• As you can notice, the slope is negative. Therefore, you can determine that it is decreasing.

Therefore, the answers are:

• Slope of the line:

m=-\frac{10}{3}

• It is decreasing.

aliya0001 [1]

Answer: The average change in field position on each run was 1\frac34 yards.

Step-by-step explanation:

Given: Total loss of field = 8\dfrac34 yards  = \dfrac{35}{5}\text{ yards}

Number of times football team carried the ball  = 5

The average change in field position on each run =  \dfrac{\frac{35}{4}}{5}

=\dfrac{35}{4\times5}\\\\=\dfrac{7}{4}\\\\=1\dfrac34 yard .

The average change in field position on each run was 1\frac34 yards.
