Question

Find the equation of linear function

f(300) =1700 and f(800) =4100

Answer 1

The points are (300,1700) and (800,4100)

Find the slope,

m =(y_2-y_1)/(x_2-x_1) =(4100-1700)/(800-300) =2400/500=24/5

Find the linear equation.

y =mx+c

y =(24/5)x+c

1700=(24/5)(300)+c

c=260

y =(24/5)x+260
