Answer:

Step-by-step explanation:
An equation of a line is given
, where m is the gradient or 
The rise indicates the change in value of y (vertical change in the graph).
The run indicates the change in value of x (horizontal change in the graph).
Let point 1 of the graph be (x,y) = (0,-34) and point 2 be (x,y) = (20,0).
Substitute point 1 into the graph to get the constant c.



∴ The equation of the line is, 
Answer:
2r(x^2-6)(x^2+6)
Step-by-step explanation:
2x^4r-72r=2r(x^4-36)=2r(x^2-6)(x^2+6)
