Question

1) what is the slope of the line that passes through the points (2,7) and (-1,3)

a. 2/7
b. 3/4
c. 4/3
d. 1/3

Answer 1

You can graph it, or just count.
7-3=4
2-(-1) = 3
The slope will be 4/3

Answer 2

\(m=\dfrac{y_2-y_1}{x_2-x_1}\)
Where,
\((x_1,y_1)\rightarrow~(2,7)\\
(x_2,y_2)\rightarrow~(-1,3)\)
