Question

Look at this graph: 100 30 20 D DO What is the slope? Simplify your answer and write it as a proper fraction, improper fraction, or integer. Work it out

Answer 1

To find the slope of a line, we need to take two point of the graph where the line crosses the corners of the grid.

We can take the following two points:

We will use the definition of the slope:

$slope=\frac{change\text{ in y}}{\text{change in x}}$

And we draw a a triangle between the points to find the change in x and the change in y:

We substitute the changes in the slope formula:

$\text{slope}=\frac{\text{change in y}}{change\text{ in x}}=\frac{3}{2}$

Answer: 3/2
