Question

A line passes through the two points (0, -2) and (9, 1). what is the y y -coordinate of the point on this line whose x x -coordinate is 12? a. -6 b. 0 c. 2 d. 4

Answer 1

Answer: 2

Explanation:

The slope of the line is

`(-2-1)/(0-9)=(1)/(3)`

So, the equation of the line is
`y=(1)/(3)x-2`.

Substituting in x=12,

`y=(1)/(3)(12)-2=2`
