Question

can you help me with number 9 and says find the slope of the line that passes through each pair of points

Answer 1

Given:

The line passes through points A ( 1,3 ) and B ( 4,7 ).

The slope of the line is calculated using the formula,

`\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ (x_1,y_1)=(1,3),(x_2,y_2)=(4,7) \\ m=(7-3)/(4-1) \\ m=(4)/(3) \end{gathered}`

Answer: Slope is 4/3.
