@triciaal please help

Answer 4

@abb0t @AlexandervonHumboldt2 @arabpride @Ashy98 help me please

Answer 5

does it make sense

Answer 6

For the first question, what it's basically asking is that you add a value for x (independent variable or x-coordinate) and then evaluate that function to get a value for y.

For instance, the first equation says \(\large y = 50x + 200\). We can start our x value with 0, which will obviously give our y-value of 0 as well (that's just to show the origin of the graph). But more precisely if we have 1 as the x value, what we do is replace x for 1 to get \(\large y = 50(1) + 200\) which is \(\large y = 50 + 200\) or \(\large \color{green}{y = 250}\). As you can see, you have your first coordinate \(\large \color{purple}{(1, 250)}\). Continue doing that same process for every other numbers that you can do.

The second one is the same thing. We can have our origin as \(\large (0,0)\). And then if we replace 1 for x, we will have \(\large y= 60(1)\) which is equal to \(\large \color{green}{y = 60}\). So a coordinate for this can be \(\large \color{purple}{(1, 60)}\). Continue doing that same process for every other numbers that you can do.

Answer 7

does the first one look like this

Answer 8

Always remember that the x-coordinate will be independent variable and y-axis is dependent variable.

Answer 9

did i do it right

Answer 10

Yes

Answer 11

But it says to label your axis

Answer 12

oh right

Answer 13

y would be total cost and x would be hours worked

Answer 14

Yes that can work. Do you have a specific word problem for this?

Answer 15

yes

Answer 16

Mrs. Solar modeled Contractor 1’s fee formula with the equation y = 50x + 200, where x represents hours worked and y represents total cost. Please use this information for problems #1-7.

Answer 17

Yes you're right about the axes labeled.

Answer 18

okay. i was confused on number two because when i graphed it, it seemed to be out of place

Answer 19

do you know what i was doing wrong. the line practically went straight up which didnt make sense

Answer 20

@calculusxy hello?

Answer 21

Gimme a moment

Answer 22

okay

Answer 23

Can you draw me your second graph so that I can see it?

Answer 24

okay 1 second

Answer 25

i cant recreate it very accurately on a pc but i dont even think this is right anyways

Answer 26

You basically start from 0.

x-value of 1:
60(1) = 60

x-value of 2, 3, 4 etc.
60(2) = 120
60(3) = 180
60(4) = 240

Answer 27

Try to plot those points and see what happens

Answer 28

okay

Answer 29

i dont understand

Answer 30

okay wait

Answer 31

do you know what i was doing wrong?

Answer 32

@HyperSniper445 agree with @calculusxy and gave a medal

Answer 33

I don't think that you understood how to evaluate that function with x because that can mislead you to get like the wrong coordinates.

Answer 34

But I think you got it now!

Answer 35

okay thank you so much im not very good in math thank you :)

Answer 36

Have a nice day!

Answer 37

You're welcome and hope you have a day as well!
