90 miles
12 gallons of gas : 360 miles
3 gallons of gas : x miles
12 / 3 = 4
360/4 = 90
We have been given a table of values of a function. We are asked to determine whether the given function is linear or nonlinear.
We know that a function is linear when its rate of change (slope) is constant.
Let us find slope for each of the given points using slope formula.


Similarly, we will find the slopes using other given coordinates.


Since the rate of change for each set of points is
, so the rate of change is constant.
Therefore, the given function is linear.
A and 90-a is the measure of the two angles
a=90-a-6
2a=84
a=42
42° and 48°
I would but I don’t want to ;/
