Question

Mary's basic wage is $20 per week. She is also paid another $2 for each hour of overtime she works.

a) If h represents the number of hours of overtime Mary works and if w represents her total wage, write an equation for finding Mary's total wage.

b) Sketch a graph of this representation with h on the horizontal axis and w on the vertical axis.

c) Create a table of data to represent this relationship.

Answer 1

$2 dollars per each our extra.
H=hours
so it would be
2h

Answer 2

$20 per week. so you get +20 by default.

Answer 3

put the overtime and the weekly wage together..you get
2h+20 correct?

Answer 4

Total Wage =overtime + weekly

Answer 5

yes, I had 20+2h=w

Answer 6

Good.

Answer 7

So thats part A.
Moving on to part B. Its quite simple. Do you know how to graph slope intercept form?

Answer 8

It's somewhat confusing to me

Answer 9

What part is confusing you? Is it graphing slope intercept form or is it that you know how to graph slope intercept but you don't know how this equation would follow through with it?

Answer 10

The form

Look at the video and see if you understand how to graph it..

Answer 12

*how to graph slope intercept form

Answer 13

yes

Answer 14

Okay good! So lets take a look back at the equation we made.
w=2h+20
This is in a disguise of slope intercept form.
y=mx+b
See the comparison?
If the equation: w=2h+20 confuses you we can easily change the variables to make the equation easier to graph.
w->y
h->m
Making the equation being used for graphing:
y=2x+20

Now..try to graph that for me..

Answer 15

would it go up 2 then to the right 20?

Answer 16

Mm...can ya graph it form me? I don't really understand that lol..

Answer 17

looks somethin like that..

Answer 18

No I was way off

Answer 19

Uh..well thats what it looks like..eh. Maybe you need more practice on graphing slope intercept form then

Answer 20

Yes I think I do, thank you for the help tho

Answer 21

your welcome :)
