Question

i need help please

The graph represents function 1 and the equation represents function 2:

A graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3.

Function 2
y = 3x + 1

How much more is the rate of change of function 2 than the rate of change of function 1?

Answer 1

this is the graph

Answer 2

For each increase in X, how much does the Function 1 in th graph Change in Y?

Answer 3

3?

Answer 4

hmm, on the graph what are these...

What is the value of Y when X=1?
What is the value of Y when X=2?

Answer 5

(1,2)
(2,3)

Answer 6

(1,3)*

Answer 7

right (x=1, y=3) is one point, what about when x=2, y = ?

Answer 8

y would still equal 3

Answer 9

rate of change = slope = how much Y changes each increase in X

Answer 10

for the graph, Y does not change, Horizontal Line, Slope = 0

Answer 11

my choices are either 1,2,3, or 4

Answer 12

For the function2:

y = 3x + 1

You can realize that is the slope-intercept form of a line: y=mx+b, where m=slope/rate of change.

Or

Use two values of X and figure out how much Y changes as X increases by 1. for example

X=1 Y=4
X=2 Y=7

Change in Y per Change in X is 4 to 7, 3

Answer 13

The first function had rate of change of 0
The second had a rate of change of 3

the difference is your answer

Answer 14

ok. thank you!
