Answer:
The side length is multiplied by
Step-by-step explanation:
we know that
The area of the original square is equal to
If the area is doubled
then
The area of the larger square is
Remember that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z ----> the scale factor
x ----> the area of the larger square
y ---> the area of the original square
so
we have
------> scale factor
therefore
The side length is multiplied by
The "m" in y = mx + b is the <u>slope.</u>
It is the number of units a point goes up, down, left, or right each time. Making the line linear/straight.
"rise" is the the number of units you go up(+) or down(-), "run" is the number of units you go to the right
For example, if your slope is:
You are going up 1 unit, and to the right 2 units
3 or
You are going up 3 units, and to the right 1 unit
You are going down one unit, and to the right 2 units
-3 or
You are going down 3 units, and to the right 1 unit
