The wall is 9 ft by 12 ft.
9 × 12 = 108
The area of the wall is 108 ft².
Not sure what the width of the wallpaper is for <:(
a: draw a rectangle an label one side 80 and the other 115
b: 1560 Yards
The standard form:

The slope-intercept form:

m - slope

b - y-intercept (0, b).
We have the point (0, 43) → b= 43.
Next point (2, 55). Substitute to the slope formula:

Therefore we have:
<em>subtract 6x from both sides</em>
