Answer:
slope = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 8) and (x₂, y₂ ) = (5, - 4)
m = 
= 
= - 2
Answer:
18 inches
Step-by-step explanation:
Rick is building a scale model of the Alamo.
We are given a scale that 3 in. = 15 ft.
The length of the Alamo is 90 feet.
What is the length of the scale model in inches?
So we know that for every 15 feet, 3 inches are actually used in the project and we need a total of 90 feet. To solve, we need to find how many times 15 goes into 90, in which the number it multiplies to will apply to the inches.
15 * ? = 90
90 / 15
6
It takes 15 6 times to get to 90, meaning that we need to multiply 3 inches 6 times to find the actual length of the scale model in inches.
3 * 6
18 inches.
