Question

How can you tell if a graph is linear or non-linear?

Answer 1

Answer:

Basically a Linear function is a function that has at least both of these:

Step-by-step explanation:

1. A slope, Requirement: rate of change stays constant)

2. One input goes to goes to only one output(however a output can have two different inputs but they must only go to that one output).

example:

x     |   y

________

0    |    25

2    |    85

4    |    145

6    |   205

The slope for that example was 60.

you can use slope intercept form to find your answer equation being:

Y = mx + b

y  =  total

m = slope

x =  domain

b = y- intercept

Answer 2

Answer:

we can determine whether a function is linear or nonlinear simply by looking at its graph! Because the rate at which y is changing with respect to x is constant in a linear function, the graph of a linear function is a line, as the name implies.
