In order to find the slope, we need the formula (y2-y1)/(x2-x1). The x and y represent the point (x,y). (-6,4) is our first point. (2,1) is our second point. (1-4)/2-(-)6 > -3/2+6> -3/8
The slope is -3/8.
Answer:
Constant.
Step-by-step explanation:
If there is only a number and no variables attached, it is a constant term, which means the term will always stay the same, and will not change.

The only logical answer is, 2 because the unit rate is value of y when x=1.
y=(1)2
y=2.
As I stated in the same question, the "Unit Rate" is not hard, it's just slope. They are trying to trick you by saying "unit rate". Your unit rate is x2.
Proof for the equations are given below.
Step-by-step explanation:
- Step 1: The diagram is made up of 1 square and 4 rectangles, and the whole figure is a square. So the area of the larger square (figure) must be equal to the sum of the areas of the 4 rectangles and 1 square. Find the area of the figure or the larger square.
Area of a square = (side length)²
Here, the length of the side of the larger square = a + b
⇒ Area of the square = (a + b)²
- Step 2: Find the sum of the areas of the 1 square and 4 rectangles.
Here, the side of the square = a - b
⇒ Area of the square (in the center) = (a - b)²
Area of a rectangle = length × width
Here, length = a and width = b
⇒ Area of the 4 rectangles = 4 × a × b = 4ab
∴ Sum of the areas = (a - b)² + 4ab
Now, both these areas are the same.
⇒ (a - b)² + 4ab = (a + b)²
- Step 3: Expand the above equation.
Left Hand Side = (a - b)² + 4ab = a² - 2ab + b² + 4ab = a² + 2ab + b²
= (a + b)²
= Right Hand Side of the equation
SOLUTION:
= 3 / 4
= 75 / 100
= 0.75
Therefore, Robert came in first for 0.75 of his race.
Hope this helps. :)
Have a lovely day! <3
