What is the area of the quadrilateral formed by the points (3,6), (0,0), (-2,9) and (1,15)? 39 square units
-39 square units
21 square units
–21 square units
The points formed are not a parallelogram

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

what? that isnt a question
