Answer:
slope -intercept form
y = -328.275 x + 3142.15
Step-by-step explanation:
Step(i):-
Given that the points are (2, 2485.6) and (6,1172.5)
The slope of the line
        [tex]m = \frac{y_{2}- y_{1} }{x_{2}-x_{1} }[/tex]
       [tex]m = \frac{1172.5-2485.6 }{6-2 }[/tex]
      [tex]m = - 328.275[/tex]
Step(ii):-
Equation of the straight line passing through the Point (2,2485.6)
[tex]y - y_{1} = m(x-x_{1} )[/tex]
y - 2485.6 = (-328.275)(x-2)
y - 2485.6 = -328.275x+656.55
 y =  -328.275x+656.55 + 2485.6
y = -328.275 x + 3142.15
Final answer:-
slope -intercept form
y = -328.275 x + 3142.15
