Adam has 28 model cars and airplanes. He has 16 model cars. The rest of his models are airplanes. Write and solve an equation to find how many model airplanes Adam has

Mathematical equation is

Adam has  models of  airplane

Step-by-step explanation:

Let the total number of models of cars and air planes be represented by "Z"

Let the total number of models of cars be represented by "X"

Let the total number of models of air planes be represented by "Y"

Now the mathematical equation showing the relation between X, Y and Z is as follows -

Given ,

Substituting the given values in above equation, we  get -

sorry i need the points

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
