Start with the slope formula.
m = y₂ - y₁ / x₂ - x₁
m = -6 - 3 / 5 - -2
m = -9 / 7
So the slope is -9/7.

Right triangle
Sin A = Opp./ Hypo. = BC/AC
Cos C = Adj./Hypo. = BC/AC
Answer is D.
Sin A = Cos C
Answer:

Step-by-step explanation:
Let
x------> the number of shirts ordered
y-----> the total cost of the order
we know that
The linear equations that represent each situation are
<u>Shirts-2-Go</u>
------> equation A
<u> Shirts PLUS</u>
------> equation B
To know how many shirts to purchase so that the total cost is the same in both companies, equate equation A and equation B
