y=- 1/3x+4 on a graph

OpenStudy (loveneenah):

to make order pairs

OpenStudy (sapphiremoon):

Are you looking for a couple of ordered pairs that satisfy the equation? To find an ordered pair for an equation, just plug in an x value and you'll get a y value, making your ordered pair, like (0, 4) and (1, 3.75) for this equation.

Cuz I to put it on a graph

OpenStudy (sapphiremoon):

(from our conversation in messages) Eh, I'm not great at it either, just a little farther along. :) To graph any linear equation, we just get a set of at least three ordered pairs and trace through and past them in both directions. We get our y values for the ordered pairs by putting different numbers in for x and finding the output. For y = -1/3 x + 4, lets try putting in 0 for x. y = -1/3 (0) + 4, -1/3 of 0 is 0, so y = 0 + 4, y = 4. That's an ordered pair, (0, 4). Great. let's try a different number. y = -1/3(2) + 4, -1/3 of 2 is -2/3, so y = -2/3 + 4, y = 3.333. Not a great number for graphing. Let's try 3. y = -1/3(3) + 4. -1/3 of 3 is -1, so y = -1 + 4, y = 3. That's a nice pair, (3, 3). Do you see where I'm going now? If you plot 3 nice points on the graph and trace through them, you have a graph of a line. @loveneenah
