# Line AB contains points A(0,1) and B(1,5). The slope of line AB is ... ?

**Solution:**

The slope formula is

m = (y\(_2\) - y\(_1\) )/ (x\(_2\) - x\(_1\) )

where the points on the line are A (x\(_1\), y\(_1\)) and B (x\(_2\),y\(_2\))

The slope is the ratio of the change in the y coordinates to the change in the x coordinates.

The two points on the line AB are A(0,1) and B(1,5)

Substituting it in the formula

m = (5 -1)/ (1- 0)

m = 4/1

m = 4

Therefore, the slope of line AB is 4.

## Line AB contains points A(0,1) and B(1,5). The slope of line AB is ... ?

**Summary: **

Line AB contains points A(0,1) and B(1,5). The slope of line AB is 4.
