1.You can recognize exponential and linear function by their graph.Linear functions are straights while exponential functions are curved lines.You can also recognize them by the change in your.If the same number is being added to y,then the function has a constant change and is linear.3:-An example of a exponential function is the growth of bacteria and A common equation,y=mx+b y=mx+b,(namely the slope-intercept form,which we will learn more about later)is a example of a linear function.2:-For constant increments in x,a linear growth would increase by a constant difference,and an experimental growth would increase by a constant ratio.

Let g = graph paper and r = ruler

1st equation: 5g + 30r = 40

2nd equation: 12g + 20r = 44

Multiply the 2nd equation by -1.5 to cancel out the r's

2nd equation: 12g + 20r = 44 x -1.5 = -18g - 30r = -66

Now add the 1st equation to that:

-18g + 5g = -13g

30r -30r = 0

40 -66 = -26

The new equation becomes -13g = -26

Divide both sides by -13

g = -26 / -13

g = 2

This means each pack of graph paper cost $2.

Now replace g with 2 in the first equation to solve for the cost of a rule:

5(2) + 30r = 40

Simplify:

10 + 30r = 40

Subtract 10 from each side:

30r = 30

Divide both sides by 30:

r = 30 / 30

r = 1

Each rule cost $1.
