A line of best fit for the data is y = 0.9x - 4.5, where x represents age, in years, and y represents hourly pay, in dollars.
Based on the data, what is the best prediction for the hourly pay of a 25 year old?
O A $17.50
OD. $22.50
O B. $18.00
O E. $32.78
O c. $19.00

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
