What is the slope of the line going through (-8,13) and (-7,9)?

5 0

Answer:

1. m = -4

2. y - 13 = -4(x + 8)

3. y - 9 = -4(x + 7)

Step-by-step explanation:

Slope m = (y2-y1)/(x2-x1)

m = (9 - 13)/(-7 - -8) = -4/+1 = -4

The point slope formula using (-8,13):

y - 13 = -4(x- -8) => y - 13 = -4(x + 8)

The point slope formula using (-7,9):

y - 9 = -4(x - -7) => y - 9 = -4(x + 7)

 Answer is C. 365
 
Step One: (Put the numbers in order from least to greatest)
300, 310, 320, 342, 355, 362, 368, 375, 375, 378, 397, 402,

Step Two: (FInd the number(s) that are directly in the middle).
- Normally it's one number, but since this is an even number (12). There's two in the middle. 362, 368.

Step Three: (Add them then divide | only do this when there's two numbers in the middle)
362 + 368 = 730.
730 divided by 2 = 365

Determine and state an equation of the line perpendicular to the lines 5x-4y=10 and passing through the point (5,12). in point-s
sergey [27]
Perpendicular lines have slopes that are negative reciprocals of one another.

slope intercept form (y = mx + b) of the first equation will help us find the slope of the first line: where m = slope

5x-4y=10
-4y=-5x + 10
y=-5/-4 x + 10/-4
y=5/4 x -2.5

if the slope of this line is 5/4 then the slope of the perpendicular line is -4/5.

Therefore with the given information we can state the equation of the second line in point slope form (y-y,) = m(x-x,)

the coordinates of (5,12) can are substituted for x, and y,

so the answer is

(y-12) = -4/5(x-5)

I hope this helped and is BRAINLIEST!

Good luck with your studies!
