Answer:

Step-by-step explanation:

recall that point-slope form of a linear equation is expressed as follows

y - y1 = m (x - x1)

where m = slope and (x1, y1) is the coordinate of any point on the line

so, here we have m = (3/5), x1 = 4 and y1 = -6

substitute these into the formula

y - (-6) = (3/5) (x - 4)

y + 6 = (3/5) (x - 4)----> answer

Answer:

$\boxed{\text{B. }y + 6 =\dfrac{3}{5}(x - 4)}$

Step-by-step explanation:

The point-slope formula for a straight line is

$y - y_{1} = m(x - x_{1})$

x₁ = 4; y₁ = -6; m = ⅗

Substitute the values

$\begin{array}{rcl}y - (-6) & = & \dfrac{3}{5}(x - 4)\\\\y + 6 & = & \dfrac{3}{5}(x - 4)\\\\\end{array}\\\text{The equation for the line is $\boxed{\mathbf{y + 6 =\dfrac{3}{5}(x - 4)}}$}$

The figure shows the graph of the equation with slope ⅗ passing through (4,-6).

four plastic bottles, each with a radius of 2 inches, are packed into a cardboard box. The glasses touch each other and the side

shepuryov [24]

The area of a 2D form is the amount of space within its perimeter. The area of the bottom of the box is 64 square inches.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or other quadrilateral, multiply its length by its width.

Given the radius of the base of the plastic bottle is 2 inches, and there are four bottles arranged as shown below, therefore, the area of the bottom of the box is,

$\rm \text{Area of the bottom of the box} = 8 \times 8 = 64\ in^2$
