Well since the line is headed to the left side, you know it has a negative slope, so B and C can be crossed out. Then, you know that point-slope form is written as y - y1 = m (x - x1)
So, you just plug in the numbers given on the graph, (4,-2)
You should come out with y + 2 = -2 (x - 4)
And that's the equation of the line in point-slope form!!! :)
Hope it helped and you understand it better!
D.) y + 2= -2 (x - 4)

Answer:
red: 9/20, 0.45, 45%
White: 15%, 0.15, 3/20
Blue: 0.4, 2/5, 40%
Step-by-step explanation:
For red: you start with 9/20. It’s best to get to a denominator of 10. So divide each number by 2. You would get 4.5/10. Then change to a percent by moving the decimal of the numerator one to the right and changing it to percent. 4.5 -> 45. -> 45%. Then for the decimal, divide 45 by 100. 45/100 = 0.45.
For white: you start with 15%. Divide by 100. 15/100=0.15. Put into a fraction with a denominator of 100. It would be 15/100. Simplify. Each number can be divided by 5, so your fraction would be 3/20.
For blue: you start with 0.4. Turn this into a fraction. Since there is one decimal place, it can have a denominator of 10. The fraction is 4/10, simplified to 2/5. Using the fraction 4/10, the percent would be 40%.
I hope this helps!
Question 1: Equiangular
Question 2: Area of the parallelogram = 48 square centimeters
Question 3: Perimeter of the rectangle = 42 ft
Question 4: Area of the trapezoid = 154 square inches
Solution:
Question 1:
The given polygon is a rectangle.
The angles of each side of the polygon is 90°.
This means all angles are equal.
Hence Option A equiangular is the correct answer.
Question 2:
Area of the parallelogram = Base × Height]
= 6 cm × 8 cm
Area of the parallelogram = 48 square centimeters
Question 3:
Perimeter of the rectangle = 2(length + width)
= 2( 15 ft + 6 ft)
= 2(21 ft)
Perimeter of the rectangle = 42 ft
Question 4:
Area of the trapezoid = 
Area of the trapezoid = 154 square inches
Rotating 90degrees is like turning something 1 quarter of a turn
