If two adjacent angles have their exterior sides in perpendicular lines, then the two angles are also perpendicular.
Both exterior and interior angles sum up from 90 - 180 degrees. Therefore, if an exterior angle is perpendicular, then the interior angle must also be perpendicular in order for them to sum up to that amount of degrees (90 - 180).
The slope represents the the number of hours after the sunrise, and the y intercept represents the temperature The linear function would y=4x+4 6.) y=4+ 10/5x 7.) y= -5 -3x
