Answer:
2. -1/2
4. 3/2
Step-by-step explanation:
Gradient = (Y1 - Y2)/(X1 - X2)
2.
Point 1: (4, -1)
Point 2: (-2, 2)
Gradient = (-1 - 2)/(4 - (-2)) = -3/6 = -1/2
3.
Point 1: (4, 6)
Point 2: (-4, -6)
Gradient = (6 - (-6))/(4 - (-4)) = 12/8 = 3/2
i believe this is the answer n(2)-7<span />
First, you must observe the figure and realize that you have a parallelogram and a rectangle.
Therefore, the total area will be the sum of the area of the parallelogram plus the area of the rectangle.
Palelogram area:
A1 = b * h
We have then
b = root ((- 4 - (- 10)) ^ 2+ (2-2) ^ 2) = 6
h = root ((- 7 - (- 7)) ^ 2+ (3-2) ^ 2) = 1
A1 = (6) * (1) = 6 units ^ 2
Rectangle area
A2 = L * W
We have then:
L = root ((1 - (- 2)) ^ 2 + (- 3 - (- 4)) ^ 2) = 3.16227766
W = root ((- 4 - (- 2)) ^ 2+ (2 - (- 4)) ^ 2) = 6.32455532
A2 = (3.16227766) * (6.32455532)
A2 = 20 units ^ 2
The total area is the sum of both ares:
A = A1 + A2
A = 6 + 20
A = 26 units ^ 2
Answer:
the area of this figure
A = 26 units ^ 2
It would be negative 250 so -250
