My name is Ann [436]

x = 2  \\ y = 7

is the answer to:

y = 11 - 2x \\ 4x - 3y =  - 13

_________________________________________

x = 5 \\ y = 2

is the answer to:

2x + y = 12 \\ x = 9 - 2y

_________________________________________

x = 3 \\ y = 5

is the answer to:

2x + y = 11 \\ x - 2y =  - 7

_________________________________________

x = 7 \\ y = 3

is the answer to:

x + 3y = 16 \\ 2x - y = 11

The equation of the line that contains diagonal HM is y = 2/3 x + 7.
nirvana33 [79]

Answer:

The slope of the line that contains diagonal OE will be = -3/2

Step-by-step explanation:

We know the slope-intercept form of the line equation

y = mx+b

Where m is the slope and b is the y-intercept

Given the equation of the line that contains diagonal HM is y = 2/3 x + 7

y = 2/3 x + 7

comparing the equation with the slope-intercept form of the line equation

y = mx+b

Thus, slope = m = 2/3

  • We know that the diagonals are perpendicular bisectors of each other.

As we have to determine the slope of the line that contains diagonal OE.

As the slope of the line that contains diagonal HM = 2/3

We also know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line.

Therefore, the slope of the line that contains diagonal

OE will be = -1/m = -1/(2/3) = -3/2

Hence, the slope of the line that contains diagonal OE will be = -3/2
