B. If two points on a line are A(11, - 1) and B(13, 3) , what is the equation of the line in point -stope form ?

Given:

Two points on a line are A(11, - 1) and B(13, 3).

To find:

The point slope form of the line.

Solution:

Point slope form: If a line passes through two points , then the point slope form of the line is

where, m is slope, i.e., .

Two points on a line are A(11, - 1) and B(13, 3). Slope of the line is

The slope of the line is 2 and it passing through (11,-1). So, the point slope form is

Therefore, the required point slope form is .

what grade level is this? need to know so i can look in my old textbooks!
