The equation is y = -1/4x - 4.
Point Slope Form: y - y1 = m(x - x1)
Given: (-4,-2) and y = 2x + 5
When you are given a line that is perpendicular, flip the slope upside down and change it to it's opposite (negative to positive etc).
Slope: -1/2
Now plug that and the point into the formula for PS form.
y - (-2) = m(x - (-4))
y + 2 = -1/2(x + 4)
y + 2 = -1/2x - 2
- 2 - 2
---------------------------
y = -1/2x - 4
The margin of error is given by the formula

Substituting numerical values,
Answer:
A 29 is the answer to the problem
The GCF of 16 and 40 is 8.
16/8 = 2
40/8 = 5
We can rewrite this using the distribute property like so:
<h3><u>8(2 + 5)</u></h3>
Using the distributive property:
16 + 40
16 + 40 = 56
We can also add inside the parentheses and multiply and we'll get the same answer.
8(7)
56
