Answer:

$option \: b. \: is \: correct.$

Step-by-step explanation:

$32 \sqrt[3]{18y} \div 8 \sqrt[3]{3y} \to this \: is \: same \: as : \\ \frac{32 \sqrt[3]{18y}}{8 \sqrt[3]{3y} } = \frac{4(18y)^{ \frac{1}{3} } }{(3y)^{ \frac{1}{3} } } \to \\ 4(6)^{ \frac{1}{3} } = \boxed{4 \sqrt[3]{6} }$

Is the relationship shown by the data linear? If so, model the data with an equation.

Harrizon [31]

The correct answer is:

The relationship is linear, and the equation is
y-5 = 2(x+7).

Explanation:

To determine if the relationship is linear, we find the slope between each pair of points. Slope is given by the formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope between the first two points is given by:

$m=\frac{9-5}{-5--7}=\frac{9-5}{-5+7}=\frac{4}{2}=2$

The slope between the second pair of points is given by:

$m=\frac{13-9}{-3--5}=\frac{13-9}{-3+5}=\frac{4}{2}=2$

The slope between the third pair of points is given by:

$m=\frac{17-13}{-1--3}=\frac{17-13}{-1+3}=\frac{4}{2}=2$

Since the slope is the same throughout the data, the relationship is linear and the slope is 2.

To write the equation, we use point-slope form, which is:

y-y₁ = m(x-x₁)

Using the first point, we have:

y-5 = 2(x--7)
y-5 = 2(x+7)
