Find any two points on the line.
<span>x=0⇒y=4<span>(0)</span>+7=7⇒</span> Point 1: <span>(0,7)</span>
<span>x=−1⇒y=4<span>(−1)</span>+7=3⇒</span> Point 2: <span>(−1,3)</span>
Step 2: Plot the two points from Step 1
Step 3: Draw a straight line through both points
Answer:
ab - b^2
Step-by-step explanation:
The area of the large rectangle is
A = l*w
=a*b
The area of the unshaded region is
A = b*b = b^2
The area of the shaded region is the area of the rectangle minus the area of the unshaded region
ab - b^2
First I need to know is the price of each potato.. Once I know the price it will be simple to find the answer.
