Logan's dollhouse is a replica of an actual house. the living room in the actual house is a rectangle that measures 12 ft by 20 ft. the living room in the dollhouse measures 9 in. by 15 in. what is the scale factor from the actual house to the doll house?

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
