Question

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?

1
2
3
4

Answer 1

@ganeshie8

Answer 2

rate of change is samem as slope

Answer 3

im not acctually typing, it just says that.

Answer 4

Ahh that happens when the site lags..

Answer 5

Look at the graph of Funtion1
It is a straight line, what is its slope ?

Answer 6

its a straight line and its constant

Answer 7

Good observation. The line is flat, not changing.

Answer 8

What is the slope of a flat line ?

Answer 9

The slope of a horizontal line is 0!

Answer 10

Very good !

Answer 11

so the rate of change of function1 is 0

Answer 12

Look at Function2

they gave you an equation of a straight line.
do you know how to find the slope when an equation is given ?

Answer 13

i guess.

Answer 14

When you make an educated guess, the chances are more for it to be a correct guess... so what is your guess ?

Answer 15

2?

Answer 16
