You need to create a chart like the one attached and put your own values in it. The teacher wants atleast 3 inputs and outputs but 4 or 5 is better. You first need to create a rule (EX: x+1=y)
The answer is 3/50. If you have Texas Instruments calculator, you type in 0.06, the 2nd button and then hit the MATH button and press enter on #1. It will convert it into a fraction for you. And 3/50 is in it's simplest form.
Y= 4x-1
If y is 1, then plug 1 in the equation,
1= 4x-1
Add 1 on both sides,
2= 4x
Divide by 4 on both sides,
x= 4/2
Reduce 4/2 to 1/2
Therefore, x= 1/2
Line them up by the decimal point
The y intercept is what the y value is when x is 0.
Set X to 0 and solve:
-2/9(0) + 1/3
0 + 1/3 = 1/3
The y-intercept is 1/3
