Question 103262: Our teacher wanted us to graph this equation: y= -3/4x+3
And she wanted us to use a "T-Chart" and I know what that is, but the fraction gets me confused. This problem was from our daily warm-up not from any textbook.

Our teacher wanted us to graph this equation:
y= (-3/4)x+3
And she wanted us to use a "T-Chart"
----------------------------
If x = 0, y = (-3/4)*0+3 = 3
If x = 4, y = (-3/4)*4+3 = -3+3=0
If x = 8, y = (-3/4)*8+3 = -6+3=-3
----------------------
Plot these points: (0,3), (4,0), (8,-3)
------------------------

maybe it would help to look at the equation this way:
y=+%28-3%2F4%29%28x%2F1%29%2B3
Now when you use your t chart you just multiply the fractions and then reduce if possible.
Lets try some numbers for x
try 4
y=+%28-3%2F4%29%28x%2F1%29%2B3
y=+%28-3%2F4%29%284%2F1%29%2B3
y=+%28-12%2F4%29%2B3
y=+-3%2B3
y=0
Ok so our first point is (4,0)
Try -4
y=+%28-3%2F4%29%28x%2F1%29%2B3
y=+%28-3%2F4%29%28-4%2F1%29%2B3
y=+%2812%2F4%29%2B3
y=+3%2B3
y=6
Ok so our next point is (-4,6)
Try 0
y=+%28-3%2F4%29%28x%2F1%29%2B3
y=+%28-3%2F4%29%280%2F1%29%2B3
y=+%280%2F4%29%2B3
y=+0%2B3
y=3
Ok so our next point is (0,3)
So if we plot these points on a graph and draw a line through them we get this:
+graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C+%28-3x%2F4%29%2B3%29+
hope this helped
