Explanation:
The slope (gradient) is the amount of up/down for the amount of along as you read from left to right.
Example:
Suppose we hade a slope of 2. This means that for 1 along we go up 2
Suppose we had a slope of -2. This means that for 1 along we go down 2.
Slope is
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Given:
Multiply both sides by 3
But
Add 3 to both sides
