Answer:
C. ![y = -x + 2](https://tex.z-dn.net/?f=%20y%20%3D%20-x%20%2B%202%20)
Step-by-step explanation:
First, find the slope, m, of the line that passes through the two given points.
Slope = ![\frac{rise}{run} = \frac{-2}{2} = -\frac{1}{1} = -1](https://tex.z-dn.net/?f=%20%5Cfrac%7Brise%7D%7Brun%7D%20%3D%20%5Cfrac%7B-2%7D%7B2%7D%20%3D%20-%5Cfrac%7B1%7D%7B1%7D%20%3D%20-1%20)
Next, determine the y-intercept, b.
The y-intercept is where the line intercepts the y-axis. The line intercepts the y-axis at y = 2. Therefore, b = 2.
Now, to get an equation of the line, substitute m = -1, and b = 2 in
.
✅The equation would be:
![y = -1x + 2](https://tex.z-dn.net/?f=%20y%20%3D%20-1x%20%2B%202%20)
![y = -x + 2](https://tex.z-dn.net/?f=%20y%20%3D%20-x%20%2B%202%20)
Calories proportional to grams
calories= k x grams
27 = k x 3
therefore constant k = 9
Answer:3.2
Step-by-step explanation:
Answer:
x-intercept is 10. It means when you buy 10 cups of coffee you run out of money
Step-by-step explanation:
The x-intercept happens when y = 0
so
0 = 20 - 2x
solving for x we get
2x = 20
x = 10
so when you buy 10 cups of coffee you run out of money
