Your tire air pressure is decreasing at a constant rate so that the air pressure is a linear function of time. Initially there is 37 pounds per square inch of air pressure. Two hours later there is 27 pounds per square inch of air pressure. What is the slope of the linear function that is air pressure?

Slope = 5

Step-by-step explanation:

the linear function can be represented by:

y = ax + b

where a is the slope.

initially there is 37 pounds per square inch of air pressure, so for x = 0, y = 37:

37 = 0a + b

b = 37

Then, after 2 hours, the pressure is 27 pounds per square inch of air pressure, so for x = 2 we have y = 27:

27 = 2a + 37

2a = 10

a = 5

So the slope is a = 5.

step-by-step explanation:

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
