Answer:

f(x) = -.4x + 6

explanation:

Simply find the slope using the formula [tex]\frac{y - y^1}{x - x^1} = m[/tex]

The b value can be found by substituting a point and then isolating b, the point i used was (1, 5.6) because that was the closest point to the start of the graph

Thank me later :)
