What linear equation will determine the length, given the area of a rectangle is 48 sq ft and the width is 6ft?
The equation is
First, we know that the area of a rectangle is equal to length times width, or
We know the area and the width, so we can solve the length.
The definition of a linear equation is simply an equation where when two points are plotted on a graph, you can make a straight line through the two points. Another way to state this is that it has a max of one unknown/variable.
First, let's plug in our values into the rectangle formula:
Now, we need
Therefore, the linear equation is:
