Answer = 50
Separate both into two different rectangles
Find the missing sides
Multiply (length x width)
Add the area of both the rectangles together
Example :
Top rectangle
10 - 6 = 4yd
4 x 8 = 32
Bottom rectangle
8 - 5 = 3yd
3 x 6 = 18
Area = 50
The y-intercept occurs when x=0.
In your equation y=1.5x, when x=0, y=0. So the y-intercept is (0,0), which is the origin.
The answer is B. Hope that helped.
