How do I create a table of values for -3x+4y=8?I already have the table constructed, but would like to double check it with you.
Solve the equation for y, thus putting the equation in slope-intercept form:
4y = 3x + 8
y = 3/4x + 2
However, in constructing a table of values, I prefer to make it as easy on myself as possible. In other words, since the slope (coefficient of x) is a fraction, pick values for x that are multiples of 4, thus making it easier to graph the coordinates on the Rectangular Coordinate system.
In my opinion, it is easier to graph these whole number values than it is fraction or decimal coordinates.
First isolate for y,
This is the equation in y=mx+c form.
Pick a domain (e.g -10 to 10) and substitute the x-values into the equation. You would have a table like this:
y | x
(And so on)
YEs this is exactly how I did it myself :) Thanx for the check!
first turn the equation into y=...
once you have this, just sub in x values. usually your domain is equally above and below zero. create a t-chart with x on the left side and y on the right, then fill it in.
continue the chart in this was for as many x values are required
