FIRST ONE TO ANSWER CORRECTLY GETS A BRAINLIEST PRE-CALC HELP

Answer 1

Answer:

C

Step-by-step explanation:

When you're writing a function from a table use the equation:

y = mx +b

We look at our the difference in each in the table.

x goes up by 1 each time, and the combines change of y is $1.50+$2 each time for $3.50 total. That's a ration of 3.50/1 or just $3.50. This is our m value.

Now we have:

y = $3.50x +b

Now we find our b value by plugging in our values from the table.

x = 1 and y = $6

$6 = $3.50(1) + b

$6 = $3.50 + b subtract $3.50 from each side

$6 - $3.50 = $3.50 - $3.50 + b

$6 - $3.50 = b

$2.50 = b

So m = $3.50 and b = $2.50 so our equation is

y = $3.50x + $2.50

The answer is C
