What is the equation of a line through the points (0,9) and (3, 0)?
9-0
O because m= 0-3 y=-3x + 9
9-0
o because m= 0-3; y=-3x + 3
because m-8-9:y=-3x+9
3-
O because m= nug: Y
X+3

Option A: The equation of a line is

Explanation:

Given that the two points are and

We need to determine the equation of the line that passes through the points and

The equation of the line can be determined using the formula,

First, we shall determine the value of the slope m.

Let us substitute the coordinates and in the slope formula.

Thus, we have,

Now, we shall substitute the slope   and the point in the formula , we get,

Simplifying, we get,

Thus, the equation of the line is

Therefore, Option A is the correct answer.
