Answer:
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(10,5)and (15,20)
The slope is
[tex]m = \frac{20 - 5}{15 - 10} = \frac{15}{5} = 3 \\ [/tex]
We have the final answer as
Hope this helps you
