Valeria drew a scale drawing of a farm. The goat pen, which is 20 meters long in real life, is 5
millimeters long in the drawing. What is the scale of the drawing?
1 millimeter :
meters

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.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
