how do i graph a fraction? like say I had y=3/4x+1, how could I create plot points that are whole numbers? please help.
Answered by Damon
do you mean
y = (3/4) x + 1
?
If so, then pick x values that are 0 and multiples of 4
if x = 0, y = 1 so (0,1)
if x = 4, y = 4 so (4,4)
that is all you need really since two points are enough for a straight line but to continue
if x = 8, y = 7 so (8,7)
if x = 12, y = 10 so (12,10)
etc

You will be very choicy to get whole number. Choose x as a multiply of 4 to get whole numbers. -4,-8,0,+4, +8 etc

can you explain it a bit more.. i don't fully understand.
Answered by Damon
When you have a four on the bottom of the fraction, multiplying by four or 2 times four or three times four or any whole number times four gets rid of the fraction. Therefore since you can find y for any x you choose, choose values for x that are multiples of four.
