3.2 Scatter Plot

There is trend line in the scatter plots. And the formula of a line in alzebra is:

y = mx + c

Here,

m is the slope,

m (higher value) - the increase is faster

m (lower value) - the increase is slower, the change is not rapid

m (negative) - the value is going downward

m value 7 means, every 1 item you add on the x axis, you should add 7 unit more to the y axis.
