The slope of the line that passes through the points (-3,-3) and (-9,5)?Write your answer in simplest form.

Slope= -4/3
Step-by-step explanation:
The points are (−3,−3) and (-9, 5)
Slope= gradient between the two points
Slope= (y2-y1)/(x2-x1)
Where y2= 5
Y1= -3
X2= -9
X1= -3
Slope= (y2-y1)/(x2-x1)
Slope= (5-(-3))/(-9-(-3))
Slope= (5+3)/(-9+3)
Slope= 8/-6
Slope= -4/3. ^w^

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.
