We will see that Annie's mistake is that the point (1, -3) does not belong to the line, the first point should be (1, 7).
<h3>
How to graph the line?</h3>
Here we have the line:
y - 3 = 2*(x + 1)
First, Annie tells you to plot the point (1,-3), this would mean that when x = 1, y must be equal to -3.
But if you evaluate the function in x = 1, you get:
y - 3 = 2*(1 + 1)
y - 3 = 2*2 = 4
y = 4 + 3 = 7
So when x = 1, we have that y = 7
From this, we can conclude that the point (1, -3) does not belong to the line, so it should not be graphed.
This is the mistake that Annie did, the first point should be (1, 7).
