Answer:

Step-by-step explanation:
Slope intercept form :
y = mx + b
m is the slope
b is the y-intercept
Let's look for m, use the formula
to determine it.


Now find b, we simply need to plug in one of our coordinates to get our answer.
(12, -9)

Solve for b :
-9 = -6 + b
-3 = b
b = -3
Our slope intercept is :

Answer:
140
Step-by-step explanation:
Area of a rhombus = GE * HF / 2
Since, ED = 10, GE = 2* ED. SO, GE = 20
Since, FD = 7, HF = 2*FD. SO, HF = 14
So, 20 * 14/2
=> 10 * 14
=> 140

➷ I'm assuming the answer is to be left in algebraic form.
Perimeter = length + length + width + width or (2 x length) + (2 x width)
Substitute the values in:
Perimeter = 2(3x - 5y - 4z) + 2(x - 3y + 5z)
Simplify:
Perimeter = 6x - 10y - 8z + 2x - 6y + 10z
Perimeter = 8x - 16y + 2z <== this is the answer
