Answer:

First equation:  y = -2x

Second equation: y = 3 - x

Solution:  (1, -2)

Step-by-step explanation:

Assuming the ordered pairs of the tables are:

<u>Table 1</u>

(-5, 10)  (-1, 2)  (0, 0)  (11, -22)

<u>Table 2</u>

(-8, -11)  (-2, -5)  (1, -2)  (7, 4)

To create a linear equation, pick 2 ordered pairs. Calculate the slope by using the slope formula, then use the points-slope form of the linear equation to form the equation.

\textsf{slope }m=\dfrac{\textsf{change in }y}{\textsf{change in }x}

\textsf{point-slope form : }y-y_1=m(x-x_1)

<u>Equation 1</u>

\textsf{slope }m=\dfrac{2-10}{-1+5}=-2

y-0=-2(x-0)\\\\\implies y=-2x

<u>Equation 2</u>

\textsf{slope }m=\dfrac{-5+11}{-2+8}=1

y+11=1(x+8)\\\\\implies y=x-3

Solution to the System

Equate the equations and solve for x:

-2x = x - 3

⇒ 0 = 3x - 3

⇒ 3x = 3

⇒ x = 1

Substitute found value of x into one of the equations and solve for y:

y = 1 - 3 = -2

Therefore, the solution is (1, -2)

Step-by-step explanation:

1) The mode means what is most common, and since the path has 22 people, it is the most common place.

2) The data is distributed into 5 different columns based on how many people use the certain column. The second column is the mode and most common spot to jog.
