Question

C(1, -7), D(5, 13) determine the slope of the line that contains the given points

Answer 1

hello

to find the slope of the line CD, let's use the formula of slope

`\begin{gathered} \text{slope}=(y_2-y_1)/(x_2-x_1) \\ y_2=13 \\ x_2=5 \\ y_1=-7 \\ x_1=1 \end{gathered}`

now we can simple input the values and solve for slope (m)

`\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m=(13-(-7))/(5-1) \\ m=(20)/(4) \\ m=5 \end{gathered}`

from the calculation above, the slope of the line CD is equal to 5
