Question

1. Find the slope of the line with the following points.a. (4,3), (6,-2)b. (7,2),3,-4)

Answer 1

hello

to solve this problem, we simply need to use the formuls of slope of a line

$\text{slope(m)}=\frac{y_2-y_1}{x_2-x_1}$

in question a

the coordinate are

$\begin{gathered} y_2=-2 \\ x_2=6 \\ y_1=3 \\ x_1=4 \end{gathered}$

let's insert the coordinates into the formula above

$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{-2-4}{6-4} \\ m=-\frac{6}{2} \\ m=-3 \end{gathered}$

the slope of the line is -3
