Question

Calculate rise and run (slope) for both and y intercept on second

Answer 1

Question 8:B
Question 5:C
For question 8, you want to can’t how much it rises first and how many spaces you have to go over second. When ever you count the amount of spaces to move horizontally you always count left to right. So you start at the point furthest to the left, and since that point is higher instead of counting up to the next point you have to count down, which means it is going to be a negative number. You count down 5 spaces, and then right 4 spaces to get to the next point which means the slope is -5/4.
For question 5, it is the same concept so from the left point you have to go down 2 and over 8, which makes the slope -2/8 but you have to simplify it to make it -1/4. The y-intercept is -1.5 because that is where the line crosses the y-axis

Answer 2

B: -5/4

Explanation:

Starting from the point on the left at (-3,-2), you go to the left 4 which is the positive direction, and down 5 which is the negative direction. This brings you to the other point at (1,-3).

Hope this helps! :)
