Supplementary Angles

Step-by-step explanation:

Supplementary Angles are given to a pair of angles that, when combined, the angle measurements will equal 180.

Two angles whose measures add up to 180 degrees are called supplementary angles.

Step-by-step explanation:

If two angles measures add up to 180 degrees, then the two angles are supplementary.

Plug in supplementary angles for "".

Two angles whose measures add up to 180 degrees are called supplementary angles.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
