Question

# Graph the equation

Hint:

### To plot the graph of an equation, first we make a table of points satisfying that equation. Then we draw an x-axis and y-axis on the graph. After that we scale both the axis according the values we get in the table. Lastly, we plot the points from the table on the graph and join them to get the required curve.

## The correct answer is: After plotting the points, we join them with a line to get the graph of the equation.

### Step by step solution:

The given equation is

y = 2x + 4

First we make a table of points satisfying the equation.

Putting x = 0 in the above equation, we will get y = 4

Similarly, putting x = 1, in the above equation, we get y = 6

Continuing this way, we have

For x = -1, we get y = 2

For x = 2, we get y = 8

For x = -2, we get y = 0

Making a table of all these points, we have

Now we plot these points on the graph.

After plotting the points, we join them with a line to get the graph of the equation.

Now we plot these points on the graph.

After plotting the points, we join them with a line to get the graph of the equation.

We can find the tabular values for any points of x and then plot them on the graph. But we usually choose values for which calculating y is easier. This makes plotting the graph simpler. We can also find the values by putting different values of y in the equation to get different values for x. Either way, we need points satisfying the equation to plot its graph
