Answer: The campers will be
from their car after 12 hours.
Step-by-step explanation:
<h3>
The missing graph is attached.</h3>
The equation of the line in Slope-Intercept form is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where "m" is the slope and "b" the y-intercept.
We can pick two points on the line graphed and substitute the coordinates into this formula to find the slope:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Choosing the points (0,4) and (2,10), we get:
![m=\frac{4-10}{0-2}=3](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B4-10%7D%7B0-2%7D%3D3)
We can susbstitute the point (0,4) and the slope into
and solve for "b":
![4=3(0)+b\\\\b=4](https://tex.z-dn.net/?f=4%3D3%280%29%2Bb%5C%5C%5C%5Cb%3D4)
Then, the equation of this line is:
![y=3x+4](https://tex.z-dn.net/?f=y%3D3x%2B4)
Since the distance in miles is represented on the y-axis and the time in hours is represented on the x-axis. we can rewrite the equation as:
![d=3h+4](https://tex.z-dn.net/?f=d%3D3h%2B4)
Finally, in order to calculate the distance in miles that the campers will be from their car after 12 hours, we need to subsitute
into the equation and evaluate. Then we get:
![d=3(12)+4\\\\d=40](https://tex.z-dn.net/?f=d%3D3%2812%29%2B4%5C%5C%5C%5Cd%3D40)
Answer:
Yes
Step-by-step explanation:
Yes, because the cost is derived from multiplying 3 by 5- and this is linear (no real exponents).
Answer:
x=−y+1
Step-by-step explanation:
Let's solve for x.
4x+4y=4
Step 1: Add -4y to both sides.
4x+4y+−4y=4+−4y
4x=−4y+4
Step 2: Divide both sides by 4.
<u>4x </u> = <u>−4y+4</u>
4 = 4
x=−y+1

Answer:
m = 2
c = -3
Explanation:
Equation of Line ⇒ y = mx +c
y = 2x - 3
m = 2
c = -3
