# What is the slope of a line that with the points (2,4) and (4,-2)?

##### 1 Answer

#### Explanation:

The line is for a strait line graph

Slope (gradient) is the amount of up or down for a given amount of along.

The state of up or down is determined as you move from left to right. Like the positive way of counting on the number line.

The degree of up/down change is measured on the y-axis (vertical number line). The degree of along is measured on the x-axis (horizontal number line).

The slope is defined as negative if it is going down (left to right) and positive if it is going up (left to right). This because of the way the numbers work.

Slope (gradient) =

So if we use rhs for right hand side and lhs for left hand side then we have:

Slope (gradient) =

Slope (gradient)=

So for every 1 along the graph line goes
