It’s a linear function because each x value belongs to only one y value and only one y value belongs to one x value
First you'll use the slop formula to find the slope.
Slope =

Slope =

Slope =

Slope =

Now we write the equation.
y = mx + b
y = -3x + 9
In this equation -3 is the slope and 9 is the y-intercept.
