Question

The slope of the line below is 2. Use the coordinates of the labeled point to find a point-slope equation of the line.

​

Answer 1

Option: D is the correct answer.

The equation of line in point-slope form is given by:

y-9=2(x-1)

Explanation:

We know that the point-slope equation of a line is given by:

y-b=m(x-a)

where (a,b) is the point from which the line passes and m is the slope of the line.

Here we are given that:

The line passes through (1,9) and slope of the line is given to be 2.

Hence,

(a,b)=(1,9) and m=2

Hence, the equation of line is given by:

y-9=2(x-1)

Therefore, the point slope intercept equation of the line is: D
