Slope = rise/run =[y2-y1]/[x2-x1]

1) slope = [90 - 30] / [12 - 4] = 60 / 8 = 15/2

2) slope = [75 - 30] / [10 - 4] = 45 / 6 = 15 / 2

The slopps are equal.

Answer: The slopes are equal.

The points are representing the same line.

Step-by-step explanation:

We know that the slope between points (a,b) and (c,d) is given by :-

m=\dfrac{d-b}{c-a}

The slope between the points (4,30)  and (12,90) will be

m_1=\dfrac{90-30}{12-4}=\dfrac{60}{8}=\dfrac{15}{2}

The slope between the points (4,30) and (10,75) will be

m_2=\dfrac{75-30}{10-4}=\dfrac{45}{6}=\dfrac{15}{2}

\Rightarrow\ m_1=m_2

We know that if the slopes are equal then the lines are parallel.

But they have one point common (4,30) so it cannot be parallel, they ust be same line .

Using translation concepts, the ordered pair that describes the location of W'' is: W''(-6,-4).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The rule for a reflection over the y-axis is:

(x,y) -> (-x,y).

Hence:

W'(-6,4).

The rule for a reflection over the x-axis is:

(x,y) -> (x, -y).

Hence:

W''(-6,-4).
