Answer:
y = -x + 2
Step-by-step explanation:
for this problem, you need the equation of a line.
the equation for a line -----> y = mx + b
- m = the slope (
)
- b = the y-intercept of the line
1) b is always the easiest to find! it's always where y = 0. when you look on the graph, you will see that when y = 0, x = 2. that's the y-intercept!
y = mx + 2
2) let's find the slope now! rise is how much the line increases or decreases (up or down), run is how far across the line moves (left to right).
- this line <u>decreases </u> 2 spaces and is moving left 2 spaces
- 2/2 = 1
y = 1x + 2 or y = x +2
3) the final step is seeing if this line is negative or positive. the way you can tell is if it increasing or decreasing. this line is decreasing and you can tell because it starts high in the left corner, and falls in the bottom right.
y = -x + 2

Find the area of the rectangle. You can find the area of a rectangle with the following formula:
w = width, and l = length.
Plug in your width and length:
The area of the rectangle is 200 square centimeters.
The area of a square is also given by width * length. Multiply the sides together:
The area of a square is 4x^2.
Because you're cutting away the square from the rectangle, you will subtract the area of the square from the area of the rectangle. The following equation will be your answer:
