Slope formula: rise over run OR (y1 - y2)/(x1 - x2)

The slope formula asks you to take two corresponding y values and x values, find their difference, and divide.

Example: Find the slope of (a, b) and (c, d)

The slope would be (a - c)/(b-d) OR (c - a)/(d - b).

It doesn't really matter which order you subtract the y-values as long as you do the same for the x-values, and vice versa.

Number 10:

Remember that a vertical line is an undefined slope!

Vertical lines increase in the y-axis, but not in the x-axis. To calculate slope you need to find the rise (y increase/decrease) over run (x increase/decrease).

So basically, the y increases forever (infinity), and is divided by 0 because the x value never increases- and you cannot divide anything by zero! You can look into why- there is a really good TedEd video I can link for you if you need it.

Therefore, the slope is undefined.

Number 11:

Straight horizontal lines always have a slope of 0- don't confuse them with vertical lines!

The rise is 0 and the run, or how much the y value increases, is infinity, because it goes on forever. 0 divided by any value other than zero is equal to zero, so the slope would be zero.

Number 12:

Right away, you can tell that this is a negative slope because it is going down on the right side of the graph! So if you don't get a negative value as your slope, you know to check your calculations.

The coordinates that are indicated by circles on the graph are (3, 4) and (4, 3).

The slope formula: (y1 - y2)/(x1 - x2)

I'll use the first point to be (x1, y1) and the second to be the values of (x2, y2)

(4 - 3)/(3 - 4) = (1)/(-1)

One divided by negative one is equal to negative 1! If you need a refresher on how to subtract or divide with negative numbers, there are a lot of great resources for that too.

So, the slope is negative 1.

Number 13:

Once again, this is a negative slope. The y values are decreasing as the x values are increasing.

The coordinates that are highlighted on the graph are (0, 4) and (3, -3).

The slope formula: (y1 - y2)/(x1 - x2)

This time, let's switch it up- I'll use the first point to be (x2, y2) and the second to be the values of (x1, y1):

(-3 - 4)/(3 - 0) = (-7)/(3)

Negative seven divided by positive three is negative 2.5.

So, the slope is negative 2.5.

I know that learning this topic can be really overwhelming, I struggled a lot with it at first- so I'm really proud you took the time to reach out and ask for explanations! I hope this helped you! Let me know if you have any questions.

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w

step-by-step explanation: hope i plz give me brainliest with the points so this is not constant cause it says last week so its clearly not every week

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
