6. Answer: y = 5x - 11
<u>Step-by-step explanation:</u>
Parallel means "same slope". y = 5x - 2 is in the form y = mx + b,
so the slope (m) = 5
Next, input the point (x₁, y₁ = 2, -1) and slope (m = 5) into the Point-Slope formula:
y - y₁ = m(x - x₁)
y - (-1) = 5(x - 2)
y + 1 = 5x - 10
y = 5x - 11

7. Answer: 
<u>Step-by-step explanation:</u>
Perpendicular means "opposite reciprocal slope". y = -3x + 7 is in the form y = mx + b, so slope (m) = -3 ⇒ m⊥ = 
Next, input the point (x₁, y₁ = 3, 5) and slope (m = ) into the Point-Slope formula:
y - y₁ = m(x - x₁)

Answer:
10 inches
Step-by-step explanation:
the box is 1000 cubic inches in volume, and 10×10×10 is 1000
The side lengths are each 10 inches tall
The box is 10 inches tall, wide, and long
Slope measures the rate of change in the dependent variable as the independent variable changes. (B) is the slope of the line. Slope means that a unit change in x, the independent variable will result in a change in (y) by the amount of (B). slope = change in (y) change in (x)rise run. Slope shows both steepness and direction.
