The coordinates of 3 of the vertices of a parallelogram are (-7,3) (-6,1) and (-4,5) what is the equation for the line containing to the side opposite the side containing the first two vertices

The first two vertices are (-7,3) (-6,1)

Slope = (3 - 1)/(-7 + 6) = -2

Opposite side of the first two vertices so the lines are parallel.

Parallel lines, slope is the same so slope is also -2

Passing thru (-4,5)

y = mx + b

b = y - mx

b = 5 - (-2)(-4)

b = 1 - 8

b = -7

Equation:

y = -2x - 7

Hope it helps.

The

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
