Question

what is the slope of the line that passes through the point (9, -1) and (4, -11) answer in simplest form

Answer 1

Answer: m= -5/2

Step-by-step explanation:
First, you would use the formula that is in the picture.


This is basically saying to use the first y value, and subtract the second y value from it. Then you do the same with the x values, by taking the first x value and subtracting the second x value.

Then, you will plug in all of the values that are given. What I did was y1= -1 and y2= 4. When you plug this into the equation, you will get -1-4.

For the x values, I did x1=-9 and x2=-11. Then, when you plug them into the equation, you will get -9- -11. Although, the two negatives cancel out to a positive, so it is -9+11.

Then you subtract both numbers, getting -5/2. This is the final answer as an improper fraction simplest form.

Answer 2

2

Step-by-step explanation:

y2-y2/x2-x1 formula for slope (x1, y1) (x2,y2)

-11-(-1)/4-9 plug into formula

-10/-5 divide
