Question

On his first birthday, Tomás was 30 inches tall. For the next year, he grew half an

inch each month. What equation models his height during that year, y, as a
function of the number of months, x?

Answer 1

y = 1/2 x + 30

Explanation:

I took the quiz! :)

Answer 2

`y = (1)/(2) x + 30`

Explanation:

y = mx + b

y is his height during that year

x is the number of months

m is the slope or rate of change, which is 1/2 inch every month

b is the y-intercept, which is 30 inches

plug everything in then you get:

y = 1/2x + 30
