To find the distance from the line with equation ( y = 9x - 3 ) to the point (-3, 2), you can use the formula for the distance between a point and a line.
The formula is:
[ \text{Distance} = \frac{|Ax_1 + By_1 + C|}{\sqrt{A^2 + B^2}} ]
Where (x₁, y₁) is the point, and A, B, and C are the coefficients of the line equation in the form Ax + By + C = 0.
In this case, the line equation is given as ( y = 9x - 3 ), so the coefficients are A = 9, B = -1, and C = 3.
Substituting the values into the formula and plugging in the coordinates of the point (-3, 2), we get:
[ \text{Distance} = \frac{|9(-3) + (-1)(2) + 3|}{\sqrt{9^2 + (-1)^2}} ]
[ \text{Distance} = \frac{|-27 - 2 + 3|}{\sqrt{81 + 1}} ]
[ \text{Distance} = \frac{|-26|}{\sqrt{82}} ]
[ \text{Distance} = \frac{26}{\sqrt{82}} ]
[ \text{Distance} \approx 2.868 ]
So, the distance from the line ( y = 9x - 3 ) to the point (-3, 2) is approximately 2.868 units.

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.
