Find the slope of the line through points (-4,-3) and (-4,5)?

Answer 1

See x-coordinate is -4 in both the points
so equation of the line is x = -4
This is a st. line parallel to y-axis
Its slope is infinite
and the angle of slope = 90degrees

Answer 2

First: you need to know the slope formula which is...

>>> m = [second y - first y] / (second x - first x]

Sec: place the points in the formula...

m = [5 - (-3)] / [- 4 - (- 4)]

m = [5 + 3] / [- 4 + 4]

m = 8/0

m = undefined

There is no slope between the points.

Answer 3

8

Answer 4

Take 5 and subtract -3 from.
Then subtract -4 from -4.
the answer would be 2 over -8. which = 1 over -4

Answer 5

Slope formula

m = y₂- y₁/ x₂- x₁

Ordered Pairs

(- 4, - 3)(- 4, 5)

m = - 3 - 5 / - 4 - (- 4)

m = - 8 / - 4 + 4

m = - 8/ 0

This proplem is undefined

- - - - - - - - - - -s-

Answer 6

As both point have the same x the line is paralel to the y axis
its equ would be x=-4 and its slope infinite. It forms 90 degree with the x axis

Answer 7

The slope formula is y2-y1/x2-x1
the result is 8/0
there is no slope (this means the line is vertical)

Answer 8

m = (y2 - y1)/(x2 - x1) ==> (5 - (-3))/(-4 - (-4)) = 8/0; which is indeterminant...therefore, the slope is said to be 'infinite', which is just another way of saying that it's a line parallel to the y-axis.

Answer 9

slope (m) = rise/run

m = y2 - y1/x2 - x1

m = 5 - (-3)/-4 - (-4)

m = 8/0

m = undefined

graph is a vertical line, so no slope

line is parallel to the y-axis

Answer 10

the equation of a line is y = mx + b where m is the slope and b is the y-intercept
m = (ya - yb)/(xa - xb)
b(-4, -3) and a(-4, 5)
m = (-3-5)/(-4+4)
impossible
