Question

What is the rate of change and initial value for the linear relation that includes the points shown in the table?

x y
1 10
2 8
3 6
4 4





Initial value: 12, rate of change: –2
Initial value: 8, rate of change: 2
Initial value: 12, rate of change: 2
Initial value 8, rate of change: –2

Answer 1

What is the relation btw slope and rate of change for linear functions?

Answer 2

Idk... @Redcan

Answer 3

I think the answer is B but I need someone to correct me

Answer 4

They are then same, if you have a linear function... so you need to find the slope btw any two points.

Answer 5

\[m=\frac{y_2-y_2}{x_2-x_1}\]

Answer 6

I'm confused lol

Answer 7

Do you know how to plot the graph?

Answer 8

you have a table of x,y values. maybe try and graph them

Answer 9

how do I graph it?

Answer 10

Draw the x and y axes.

Answer 11

just put point on a graph.

Answer 12

Do you have a pencil and paper?

Answer 13

nope I dont :/ I'm trying to get this assignment turned in but I'm stuck on this question

Answer 14

Always do math with a pencil and paper from now on.

Answer 15

Redcan has started the graph for you above.
Fill in the rest of the points.
The "initial value" is where the line should cross the y-axis
The rate of change is -2 by using the slope formula.

Answer 16

Any questions @xxlyh?

Answer 17

still solving but thank you! ill let you know if I have any

Answer 18

Solving is what math is all about :-)

Answer 19

ahh so it's D @skullpatrol

Answer 20

Nope.

Answer 21

darn it xD I'll try again

Answer 22

wait so the rate of change is -2? by using slope formula

Answer 23

Yes. I gave you half the answer.

Answer 24

I got rate of change -2 and initial value 12...... am I right ><

Answer 25

Yes.
