To find the slope of the line, use the coordinates of the given points on the following formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]Where m is the slope, y1 and y2 are the y coordinates of the points and x1 and x2 are the x coordinates of the points:
[tex]m=\frac{6-4}{7-5}=\frac{2}{2}=1[/tex]The slope of the line is 1.
