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)}=(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=(y_2-y_1)/(x_2-x_1) \\ m=(-2-4)/(6-4) \\ m=-(6)/(2) \\ m=-3 \end{gathered}`

the slope of the line is -3
