Octagon has 8 sides so the sum of the angles of the octagon is 180(8-2)=180 (6)=1080 degrees
Given the points (-1,6) and (3,5).
The formula to find the slope is

Take

Plug the values into the formula and find the slope.

The slope-intercept form is y = mx+b.
Plug the value of m.

ThusConsider the point (-1,6). Substitute -1 for x and for y into the equation.

Thus, the equation of the line in slope intercept form is

82.693
the rule is when its 4 and under round down and 5 and up round up
