$A(x)=\frac{6}{5}x^2$

Step-by-step explanation:

Let

y ----> the length of the board

x ----> the width of the board

we know that

$\frac{y}{x}=\frac{6}{5}$

$y=\frac{6}{5}x$ ----> equation A

The area of the board is

A=xy ----> equation B

substitute equation A in equation B

$A=x(\frac{6}{5}x)$

$A(x)=\frac{6}{5}x^2$

To reflect a point over the x-axis, you simply negate the y-value of the point. Thus, your new point would be (4,--1), which after you take out the double negative that cancels, you'd have (4,1).
