A scale drawing of a school bus has a scale of 1/2 inch to 5 feet. If the length of the school bus is 4 1/2 inches on the scale drawing, what is the actual length of the bus? Explain or show your reasoning. *

This is based on simple ratio & scales where a figure on a scale is used to represent the true figure on another scale.

Actual length of bus = 45 ft

The scale drawing is given by;

½ inch to represent 5 ft

Simplifying this fraction gives 45 ft

4½ inches represents 45 ft

Actual length = 45 ft

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

it has the same slope and a different y-intercept

hope this : )
