Each equation will have it's own input/ output table, where you put in a value for y and get a value for x or put in a value for k and get a value for y For example : y = -7 + 3x Y | X _|____ 0 | 7/3. 1 | 8/3. -7 | 0. (unfortunatly the WikiAnswers cannot be formatted as I'd like but the above should be a table with Y valyues on the left and X values on the right) Now do the same for the other equation: y = 5x - 13 Y | X _|____ 0 | 13/5. 1 | 12/5. -13 | 0.
3x + y = -4 -3x -3x y = - 4 -3x now plug in points!+++To clarify the principle, re-arrange the equation so it reads as "y = [something done to x]" then calculate a table of points for the plot itself.
No, an equation needs an "=".

It is 4.

3x + 2y = 8 This is an equation. It could be the equation of a line.
3x^-2 -3x^2 is not a quadratic equation because it does not take the form ax^2 +bx+c.
The answer has been right under your nose all this time.The equation of y equals -3x isy = -3x
No, an equation needs an "=".

The equation (3x + 8 = 3x - 5) has no solutions because when you simplify it, you subtract (3x) from both sides, resulting in (8 = -5). This statement is false, as 8 does not equal -5. Since the equation leads to a contradiction, it indicates that there are no values of (x) that can satisfy it. Thus, the equation has no solutions.
