The slope is y over x,

From the dot if you move 1 up and 3 to the right you would be at the point(0,-2) which would be the y intercept.

The equation would be y = 1/3x-2

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

95.03 is the answer. hope this !
