Question

Help because I DONT know how to even start

Answer 1

Answer:

2/3 for the first one

Step-by-step explanation:

The way I learned how to do it is to find two points on the line that are on one spot. Lets use the points -4,-1 and -2, 1 for the first question. Now, you want to find something called rise and run. So, you are going to start from the point -4,-1, and go up until you are on the y axis of 1 (because that is where the other point is on) Basically, you just went up 2 points, so that is your rise. Next, you have to move 3 points to the right to get to the other point -2,1. 3 is your run. Now, you have the number 2/3. Usually, you would simply your fraction, but you can't do that for this one. So, your answer would be 2/3. You could also start from the point -2,1 and go down 2 points, which gives you -2, and left 3 points, which gives you -3. Because going right and up = positive number. Down and left = negative number. Now, you have -2/-3. But you can simplify this one by dividing them by -1. So, you would still get 2/3; but I just think it's easier to do it the other way. Also remember that you ALWAYS do rise first (up and down). Sorry for the lengthy answer, and comment if you have any questions or need me to do another question. :)

Answer 2

Slope is rise/run or y2-y1/x2-x1. So to find the slope, find two points where the point is exact, then do the equation. That's the best I can explain, sorry if this doesn't help at all.
