y = 740x - 400

Step-by-step explanation:

You need to find what b(the y-intercept) is in the equation.

y = mx + b, where x is the time in hours and m is your slope

They told us the slope m(the rate of change), which is constant at 740 meters per hour. Think of a straight line with a positive slope. We just need to find b.

We know that when x = 1.5, y = 710 meters above sea level. Write this as (1.5, 710) and substitute in your equation to find b.

y = 740x + b

710 = 740(1.5) + b

710 = 1110 + b

-400 = b

Now put together the entire equation since you have all the info you need using the slope intercept form: y = mx + b

Therefore, y = 740x - 400

x =72

y =67
