Question

amber operates Kiddy land day care she charges $5 to pick up a child and $3 an hour to take care of it.
A. graph the data in the table describe your graph B.write an equation for a line passing thought the data

Answer 1

The fixed cost is $5, so b = 5

The variable cost is $3, so m = 3

y = mx+b

y = 3x + 5

So the equation of the line is y = 3x + 5

Finding the equation is useful for finding points on the line in order to graph

Answer 2

y = 3x + 5 has a y-intercept of (0,5), so that's one point on the graph

plug in x = 1 to get

y = 3x + 5

y = 3*1 + 5

y = 3 + 5

y = 8

So the point (1,8) is also on the line

Answer 3

oh i guess you could also use the table to help graph

Answer 4

oh no thais is great thanks

Answer 5

you're welcome
