Given the two points (0,4) and (2, 6), what would the numerator of the equation for slope be?

Answers

The numerator of the equation for slope would be 2.

What is the slope?

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

The slope of the line is calculated as follows:

m = Δy/Δx

Given that the line that passes through the points  (0,4) and (2, 6),

Therefore, the slope of the line is

m = Δy/Δx

m = (6 - 4)/(2 - 0)

m = 2/2

When we simplify it, then we get the;m = 1

Hence, the slope of the line is 1 So the numerator would be 2

To know more about the Slope of the line here;

The slope equation is (y^2-y^1)/(x^2-x^1)

In (0,4) and (2,6), 4 and 6 are y values, while 0 and 2 are x values

So y^2 would be 6 and y^1 would be 4

x^2 would be 2 and x^1 would be 0

Plug it in the equation would be (6-4)/(2-0)

So the numerator would be 2

when you solve a problem by working backward, what does your answer represent? how can you check your answer?

Answers

Lets say you have an addition problem

3 + 7 = ?

To figure that you can just add in your head since its easy.

3 + 7 = 10

You can work backwords to check to see if your awnser is right.

When you work backwards you do the opposite of what you are doing, so if your adding the opposite would be subtracting, and if your multiplying than the opposite would be dividing.

So you could work it out like this:

(Regular⬇️)
3 + 7 = 10
(Backwards⬇️)
10 - 7 = 3

And if you get the same numbers that were in the original awnser than you are correct! Hope this helps!!!!
