Look at the picture.

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

m=\dfrac{\Delta y}{\Delta x}

We have y=\dfrac{4}{5}x-1

b=-1\to(0,\ -1)

The Cheer Squad is raising money to pay for their trip to the State Finals. They already have $1200 and they are selling really
Vlad [161]

Answer:

10c + 1200 ≥ 3000, c≥ 180

Step-by-step explanation:

We know that they need at least $3000; meaning, it may be $3000 or more. This leaves us with eliminating the bottom two choices.

We then look at the first two choices. If we were to subtract from 1200, we would not know the total income amount that has been gained. It would also eventually give us negative numbers. We cannot have a negative amount earned. Instead, we would use the 10c+1200 because this would allow us to visualize that it needs to be greater than or equal to 3000
