The speed of sound through air is linearly related to the temperature of the air. If sound travels at 320 m/sec at 0°C and at 356 m/sec at 40°C, construct a linear model relating the speed of sound (s) and the air temperature (t). Interpret the slope of this model.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
