The distributive property tells you
.. 5(x +z) = 5x +5z
we know that
The formula to calculate the slope between two points is equal to
![m=\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
in this problem we have
![A(-1,3)\ B(4,-7)](https://tex.z-dn.net/?f=A%28-1%2C3%29%5C%20B%284%2C-7%29)
substitute in the formula
![m=\frac{-7-3}{4+1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-7-3%7D%7B4%2B1%7D)
![m=\frac{-10}{5}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-10%7D%7B5%7D)
![m=-2](https://tex.z-dn.net/?f=m%3D-2)
therefore
<u>the answer is the option A</u>
![m=-2](https://tex.z-dn.net/?f=m%3D-2)
Answer:
(0,4)
Step-by-step explanation:
Subtract the first equation from the second, obtaining y = 4. Then substitute 4 for y in the first equation, obtaining x + 2(4) = 8; it follows that x = 0.
The solution is (0,4).
Answer:
15
Step-by-step explanation:
H - 7
When H = 22, replace H with 22 in the equation.
22 - 7 = 15
