Agame piece used in a math game is shaped like a right trapezoid.

what is the area of the game piece?

We can find the area using two ways.
First way:
There is a square and triangle.
The square is a 3 by 3.
3×3=9
The triangle is a 3 by 7.
3×7× .5
10.5
10.5+9
19.5 in²
Second way
The formula to find the area of a trapezoid is:
(b+b)×h/2
Let's fill the information in.
(3+10)×3/2
13×1 1/2
19.5
So the area of the game piece is 19.5 in².

Whats your question

Y= -2x-1 the negative in front of the 2 is because the slope is negative and the -1 is because it’s down 1 on the y axis.
