What is the slope of the line on the graph?
we know that
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
in this problem we have
[tex]A(-1,-7)\ B(1,5)[/tex]
substitute the values in the formula
[tex]m=\frac{5+7}{1+1}[/tex]
[tex]m=\frac{12}{2}[/tex]
[tex]m=6[/tex]
therefore
the answer is
the slope of the line is [tex]6[/tex]
