Answer:
F = -20h + 450
Step-by-step explanation:
To find the linear function, we will use the coordinate points (1, 430) and (2, 410)
Get the slope;
m = ΔF/Δh = 410-430/2-1
m = -20/1
m = -20
Get the y intercept b
Substitute m = -20 and (1, 430) into y = mx+b
430 = -20(1) + b
430+20 = b
450 = b
Swap
b = 450
Get the required equation
y = -20x + 450
replace x with h and y with F
F = -20h + 450
Hence the required equation is F = -20h + 450
