Two airplanes are each traveling at a constant speed. The table below shows the total number of miles the first airplane traveled as a function of time.

The equation y=ax represents the total number of miles, y , traveled by the second plane as a function of the numbers of hours, x .

If the second plane is traveling faster, then what must be true about a ? Show your work, and explain your reasoning.

Type your answer in the box below.

6.5

step-by-step explanation:

you said it was in the question

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

the second option

step-by-step explanation:

4y - 6 + y^2 - 9 = y^2 + 4y - 15
