HELP PLEASEEEE!! First correct answer gets brainliest ! ​
mylen [45]

Answer:

2

Step-by-step explanation:

The slope of a line is rise/run.

First, you must choose any two points on the line.

Rise is how many spaces a line moves upward or downward from one point to another.

The run is how many spaces a line moves left or right from one point to another.

It is given that from point M to point N, the line moves up 4 spaces and runs to the right 2 spaces.

  • 4 = rise
  • 2 = run
  • Slope = 4/2, which can be simplified to 2, because 4 divided by 2 is 2.

BRAINLIESTTT ASAP !! PLEASE HELP ME :)

Answer:

Option 2, (y = 4/6x - 4)

Step-by-step explanation:

Knowing that m acts as the slope in general, we can conclude that part of the equation is as such:

y = 4/6x

Now we are given coordinate (0, - 4) so that here x = 0 and y = - 4. Let's substitute these values into the prior equation:

y = 4/6x

-4 = 4/6(0)

-4 = 0

Now in order for y (-4) to be equal to the opposite side of the equation you would have to add -4:

-4 = 0 - 4

-4 = -4

That would mean the equation represents:

y = 4/6x - 4
