You are moving in the path of a parabola.

The conic section  is parabolic - the street is the directrix  and the mailbox is the focus.

Answer:

x = -1 and y = -3

Step-by-step explanation:

The given equations are :

2x+3y= -11 ...(1)

8x -2y= -2​​ ...(2)

We need to solve the equations.

Multiply equation (1) by 4.

8x+12y= -44 ...(3)

Subtract equation (2) from (3).

8x+12y-(8x -2y) = -44-(-2)

8x+12y-8x +2y = -42

14y = -42

y = -3

Put the value of y in equation (2).

8x -2(-3)= -2​​

8x+6 = -2

8x = -8

x = -1

So, the values of x and y are -1 and -3 respectively.

Beatrice calculated the slope between two pairs of points. She found that the slope between ( ( -3, 3 , -2) 2 ) and (1, 0) ( 1 ,
Alchen [17]

Answer:

These points may or may not be on the same line.

Step-by-step explanation:

The first set of points is: (-3, -2) and (1, 0)

The second set of points is (-2, -1) and (4,2)

Slope of first two points is:

Slope=\frac{0-(-2)}{1-(-3)}=\frac{2}{4}=\frac{1}{2}

Slope of second set of points is:

Slope=\frac{2-(-1)}{4-(-2)}=\frac{3}{6}=\frac{1}{2}

The points are on the lines with the same slopes. But this does not guarantee that these points are on the same line as two parallel lines will also have the same slopes. In order to confirm the conclusion Beatrice need to find the y-intercept or the equation of the lines. If the y-intercept or the equation of lines is same in both cases this would mean that all 4 points are on the same line, else they would be on 2 different lines.
