# How do you graph #3x-7y=21# using a table of values?

the straight line passes through two points (0, -3 ) and (7,0).

3x - 7y =21 is a linear simultaneous equation. For each value of x, there will be different value of y. when x =o, 3 X 0 - 7 X y = 21 or, o - 7y = 21 or, -7y = 21 or -7y/-7 = 21/-7 or, y = -3 similarly for y = 0, 3x - 7 X0 = 21 or, 3x =21 or, 3x/3 = 21/3 or, x = 7 Hence the straight line passes through two points (0, -3 ) and (7,0).

To graph the equation (3x - 7y = 21) using a table of values, you can choose values for (x), plug them into the equation to find the corresponding values for (y), and then plot those points on a coordinate plane. Here's a step-by-step guide:

- Choose a few values for (x), such as -3, 0, 3.
- Plug each value of (x) into the equation to find the corresponding values for (y).
- Calculate (y) for each (x) value: For (x = -3): (3(-3) - 7y = 21) → (y = -6) For (x = 0): (3(0) - 7y = 21) → (y = -3) For (x = 3): (3(3) - 7y = 21) → (y = 0)
- Plot the points ((-3, -6)), ((0, -3)), and ((3, 0)) on a coordinate plane.
- Draw a straight line passing through these points to represent the graph of the equation (3x - 7y = 21).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
