Question

What is the slope of the line on the graph below? On a coordinate plane, a line goes through points (negative 2, negative 3), (negative 1, negative 1), (0, 1) and (1, 3). –One-half One-half 1 2

Answer 1

2

Explanation:

Take any two points -- I'm using (0, 1) and (1, 3). You can think of slope as (change in y)/(change in x), or simply rise/run. (3-1)/(1-0) is equal to 2.

*Note: (-1/2,1/2) is not in the same line as the other four points.

Answer 2

2

Explanation:

We can use 2 points to find the slope

m = (y2 -y1)/(x2-x1)

Using ( 0,1) and (1,3)

= (3-1)/(1-0)

= 2/1

= 2
