Y=ax+b
for x=7, y=2
7a+b=2

for x=2, y=12
2a+b=12

7a-2a+b-b=2-12
5a= -10
a= -10/5
a=-2
2a+b=12
2*(-2)+b=12
-4+b=12
b=12+4
b=16
y=-2x+16

Find the area of the shaded region. Need a Hint? 40 square meters 23 square meters 56 square meters 12.5 square meters
sesenic [268]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any diagram so I'll assume we are talking about a square. If so, then the area of the square is given by:

A=s^2 \\ \\ s:Side \ of \ the \ square

From the figure below, we know that the side of the square is:

s=20m

So the area can be found as:

A=(\sqrt{40})^2 \\ \\ A=40m^2

Finally:

<em>The shaded region has an area of 40 square meters</em>
