Question

How do you find the slope of a graph? Give an example with your explanation.

Answer 1

Given:

The objective is to find the explain the slope of a graph with an example.

The slope of a graph can be identified by the formula,

`m=\frac{y_2-y_1_{}}{x_2-x_1}`

Here, x and y represents the any two coordinates of a graph.

Consider a graph of straight line with two coordinates.

Consider,

`\begin{gathered} (x_1,y_1)=(2,1) \\ (x_2,y_2)=(4,2) \end{gathered}`

Now substitute the values in the formula of slope.

`\begin{gathered} m=(2-1)/(4-2) \\ m=(1)/(2) \end{gathered}`

Hence, the slope of the graph is 1/2.
