Answer:
The equation of the line in point-slope form is ![y - 1 = m(x + 1)](https://tex.z-dn.net/?f=y%20-%201%20%3D%20m%28x%20%2B%201%29)
Step-by-step explanation:
Equation of a line:
The equation of a line, in point-slope form, is given by:
![y - y_0 = m(x - x_0)](https://tex.z-dn.net/?f=y%20-%20y_0%20%3D%20m%28x%20-%20x_0%29)
In which the point is given by
and m is the slope.
The slope of the line below is 3.
This means that ![m = 3](https://tex.z-dn.net/?f=m%20%3D%203)
(-1,1)
This means that
.
Equation of the line:
![y - y_0 = m(x - x_0)](https://tex.z-dn.net/?f=y%20-%20y_0%20%3D%20m%28x%20-%20x_0%29)
![y - 1 = m(x - (-1))](https://tex.z-dn.net/?f=y%20-%201%20%3D%20m%28x%20-%20%28-1%29%29)
![y - 1 = m(x + 1)](https://tex.z-dn.net/?f=y%20-%201%20%3D%20m%28x%20%2B%201%29)
The equation of the line in point-slope form is ![y - 1 = m(x + 1)](https://tex.z-dn.net/?f=y%20-%201%20%3D%20m%28x%20%2B%201%29)
Answer:
36
Step-by-step explanation:
6r + 6 - 4s
r = 7
s = 3
6(7) + 6 - 4(3)
42 + 6 - 12
(remember PEMDAS, adding/subtracting left to right)
48 - 12 = 36
therefore the answer is 36
hope this helps ! :)
We can start by solving for 10-5a+(18-b). By plugging in a and b, we get
10 - 10 + (18 - 11)= 7
28 ÷ (a × 2) = 28/4 = 7
20 + b − (4 × a) = 31 - 8 = 23
49 − 43 + (a ÷ a) = 49 - 43 + 1 = 7
30 − 25 + (b − 9) = 5 + 2 = 7
50 ÷ a − (b + 20) = 25 - 31 = -6
So, 28 ÷ (a × 2), 49 − 43 + (a ÷ a), and 30 − 25 + (b − 9) will all have the same answer as 10−5a+(18−b)
