Can’t get 3 Can Simone check my answers snd help with 3? Thanks!’
#3. -3 is my answer.
Your right, she has them 100% correct :)
Sorry meant someone
all look good to me
Sure! Let's go through each question one by one and find the slope for each.
1. Look at the graph
To find the slope of a line, we need to determine the change in the y-coordinates over the change in the x-coordinates. In this case, the given points are (-1, -2) and (2, 1). The change in y-coordinates is (1 - (-2)) = 3, and the change in x-coordinates is (2 - (-1)) = 3. Therefore, the slope of the line is 3/3 = 1. Since the slope is positive, the correct answer is A. Positive.
2. Finding the slope of the line
The given points are (1,-2) and (3,2). Again, we need to calculate the change in the y-coordinates and the change in the x-coordinates. The change in y-coordinates is (2 - (-2)) = 4, and the change in x-coordinates is (3 - 1) = 2. The slope of the line is 4/2 = 2. Therefore, the correct answer is B. 2.
3. Finding the slope of the line
The given points are (2,1) and (1,4). To find the slope, we need to calculate the change in y-coordinates and the change in x-coordinates. The change in y-coordinates is (4 - 1) = 3, and the change in x-coordinates is (1 - 2) = -1. The slope of the line is 3/-1 = -3. Therefore, the correct answer for this question is A. -3.
4. What is the slope of the line that goes through (6,5) and (3,1)?
Again, we need to find the change in the y-coordinates and the change in the x-coordinates. The change in y-coordinates is (1 - 5) = -4, and the change in x-coordinates is (3 - 6) = -3. The slope of the line is -4/-3 = 4/3. Therefore, the correct answer is C. 4/3.
5. The slope of the line that goes through (-3, -5) and (-3, -6) is ______.
To find the slope, we once again calculate the change in the y-coordinates and the change in the x-coordinates. In this case, the change in y-coordinates is (-6 - (-5)) = -1, and the change in x-coordinates is (-3 - (-3)) = 0. When we have a change of zero in the x-coordinates, the slope is undefined. Therefore, the correct answer is D. undefined.
Based on the explanations above, your answers for questions 1, 2, 4, and 5 are correct. For question 3, the correct answer is A. -3.
