Question

If a line passes thru the points (4,5) and (2,9) the slope of this line is

Answer 1

m=-2

Step-by-step explanation:

If a line passes through the points (4,5) and (2,9): to calculate the slope, use the formula below:

`\text{Slope,m}=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}}`

Substituting the points, we have:

`\begin{gathered} m=(9-5)/(2-4) \\ =(4)/(-2) \\ =-2 \end{gathered}`

The slope of this line is​ -2.
