12. Dominic drives a taxi. He charges a $2 flat fee plus $1.50 per mile.
r-ruslan [8.4K]

Answer:

The y-intercept represents the flat fee.

Step-by-step explanation:

The y-intercept on the graph would be the point at which the line cuts across or intercepts the y-axis. At this point, the value of x (miles travelled) would be 0. The y-intercept in this case, would be the flat fee which is given as $2.

At x = 0, f(0) = 2.

The y-intercept represents the flat fee on the graph of f(x).

4x + 1/3 y 2 what is the value of the expression above when x = 2 and y = 3
GenaCL600 [577]
Hoi!

To solve this, first plug in the values for x and y.

x = 2, so anywhere you see x, put 2 in its place.

y = 3, so anywhere you see y, put 3 in its place.

4(2) +  \frac{1}{2}(3)

4 × 2 = 8

\frac{1}{2} × 3 = 1 \frac{1}{2}


8 +1 \frac{1}{2} = 9 \frac{1}{2}

9 \frac{1}{2} is your answer.
