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,

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

Answer: Slope is 4/3.
