Answer:
16
Step-by-step explanation:
separate into 4 triangles. 2x1= 2
triangle area formula= 1/2 l x w
3x4=12 12+4 is 16
-16y = -12x + 48
y = .75x -3
The rate of change is .75 or 3/4.
Answer: infinite
Step-by-step explanation: since they have the same slope and y interscept it is a coincident line and has infinite solutions
y= 4-x
y= 4-x
