There are two ways to do this.
The first is you plug in the x-value from the point in the table and see if that gives you the y-value from the same point.
For example, your first point is (5,49), so plug in x=5:
y = -5(5)+2 = -25+2 = -23
Since that's not the y-value in (5,49), then (5,49) is not a solution for the equation.
The other option is you plug in both the x-value and the y-value to see if you get a true statement. (A solution will make the equaiton a true statement.)
For example, the first point is (5,49), so you'd plug in x=5 and y=49:
49 = -5(5)+2
49 = -25 + 2
49 = -23
Since that's not true, (5,49) is not a solution.
You'll notice you're basically doing the same thing, it's just whether you plug in one value or both and that's your choice.
Answer:

Step-by-step explanation:
To solve a formula for one of its variables do that
- Separate it on one side and the other terms on the other side
- Make its coefficient equals 1
Let us use these steps to solve our question
∵ V =
b²h
→ Underline b
∴ V =
<u>b²</u>h
→ Multiply both sides by 3 to cancel the denominator on the right side
∴ 3V = <u>b²</u>h
→ Divide both sides by h to move it to the other side
∴ 
→ To find b take √ for both sides
∴ 
→ The square root will cancel the power 2 of b
∴ 
→ Switch the two sides
∴ 
A) triangle c, has the largest area
b) a= 1/2 (3) (3) a= 4.5
