A section in a stained glass window is shaped like a trapezoid. The top base is 3 centimeters and the bottom base is 1.5 centimeters long. If the area of the section of glass is 6.3 square centimeters, how tall is the section ?

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
