The area of the banner, expressed in simplest form, is: <em>(9 + 3x) ft²</em>
<h3>How to Determine the Area of a Rectangle</h3>- The area of a rectangle = length × width
The banner given in the image below has a rectangular shape. So, the area of the banner will be determined using the area of a rectangle.
- length = (3 + x) ft
- width = 3 ft
Area of the banner = (3 + x)3
Area = (9 + 3x) ft²
Therefore, the area of the banner, expressed in simplest form, is: <em>(9 + 3x) ft²</em>

First you need to find the slope of the line containing those 2 points using the slope formula. Filling in with our info we have 
. So the slope is -1.5. Now we need to find out the rest of the info, mainly the y-intercept. The line appears to go through the y axis at (0, 0), but let's make sure. We will use the slope we just found and one of our points to solve for the y-intercept. I picked point (4, -6). Filling in to solve for b we get -6 = (-1.5)(4) + b. Doing the multiplication on the right gives us -6=-6 + b. Add 6 to both sides to get that b = 0. Now let's use that and the slope we found to rewrite the equation in slope-intercept form. y = -1.5x + 0 or y = -1.5x and there you go!
