To graph this line, we can simply pick 2 points and draw a smooth line through it.
Since x is the independent variable, we pick a value of x and find its corresponding y value.
This can be done infinite number of times.
But we only need two points to graph a line.
Let's take x = 0
So, we have:
y = 2x + 3
y = 2(0) + 3
y = 0 + 3
y = 3
Now, let's take x = 2,
So, we have:
y = 2x + 3
y = 2(2) + 3
y = 4 + 3
y = 7
So, the ordered pairs would be:
(0, 3)
AND
(2, 7)
We graph it and draw a smooth curve. Shown below:
