Line AB contains points A (1, 2) and B (-2, 6). the slope of line AB is?

Solution:

The slope formula has to be used to determine the slope of a line with two points given by 

m = y₂ - y₁/ x₂ - x₁

Where m is the slope of line and (x₁, y₁) and (x₂, y₂) are the two points of the line.

Now let us substitute A (1, 2) and B (-2, 6) in the formula

m = (6 - 2)/ (-2 - 1)

m = 4/-3

m = -4/3

Therefore, the slope of line AB is -4/3.

Line AB contains points A (1, 2) and B (-2, 6). the slope of line AB is?

Summary:

Line AB contains points A (1, 2) and B (-2, 6). The slope of line AB is -4/3.
