Answer:
Y=mx+b Is a linear equasion because if you plot the x and y on a graph it always shows a straight line.
Step-by-step explanation:
For example, y=7x+9,
When x is 1 y is 16, and
when x is 2 y is 23.
When you put those two points on a graph and connect the dots with a ruler, you get a straight line, and you will automatically find that when x is 3 y is 30.
Scale for y - 1:1
Scale for x - 1:10
Reason- so that i can plot the points on the graph without any modification to the given one.
Now plot the points on the graph using the scale. I cant obviously do that here.
Answer:
3x^3 + 3x^2 - 27x - 27
