Answer:
Approximately 12.04 units.
Step-by-step explanation:
The find the distance between any two points, we can use the distance formula, which is:
We have the points (2,7) and (-6,-2). Let's let (2,7) be (x₁, y₁) and let's let (-6, -2) be (x₂, y₂). Substitute:
Subtract:
Square:
Add:
Approximate
So, the distance between (2,7) and (-6,-2) is approximately 12.04 units.
And we're done!

Answer:
1/6 mph
Step-by-step explanation:
To find miles per hour, divide miles by hours.
(1/8 mi)/(3/4 h) = (1/8×4/3) mi/h = 1/6 mi/h
The snail's speed is 1/6 miles per hour.
12.
y = kx
8 = -4k
so k = -2
y = -2x
y = -2 (7)
y = -14
13.
y = kx
15 = 6k
so k = 15/6 = 2.5
y = 2.5x
y = 2.5 (7)
y =17.5
14.
y = kx
3 = 9k
so k = 3/9 = 1/3
y = 1/3x
y = 1/3 (7)
y =7/3
15
y = kx
-4 = 4k
so k = -4/4 = -1
y = - x
y = - (7)
y = -7
16.
Yes. y varies directly with x
slope = (3+6)/(2+1) = 9/3 = 3
y = mx + b
-6= 3(-1) + b
b = -6 + 3 = -3
equation y = 3x -3
17.
Yes
slope = (2.5 - 7.5)/(-1+3) = -5/2 = -2.5
y = mx + b
7.5= -2.5(-3) + b
7.5 = 7.5 + b
so b = 0
equation
y = -2.5x
