What is the slope of the line that passes through the points (-2,5) and (1,4)?
a. -3
b. -2
c. -1/3
d. 1/3
I just need to know how to solve this problem or a simple formula to help me know how to solve these types of questions?
Thanks,

slope is
change in y
-----------------
change in x
Moving from (-2,5) to (1,4)
y changes by -1
x changes by 3
So, now you can get the slope.
Hard to believe this was not clearly explained and demonstrated in your text.
Or heck, remember that google is your friend. No need to wait for help here, when google can give you dozens of explanations and images.
To find the slope of a line that passes through two points, you can use the formula:
slope = (y2 - y1) / (x2 - x1)
In this case, the coordinates of the first point are (-2, 5), and the coordinates of the second point are (1, 4).
Plugging these values into the formula, we get:
slope = (4 - 5) / (1 - (-2))
Simplifying further:
slope = -1 / 3
So, the slope of the line that passes through the points (-2, 5) and (1, 4) is -1/3.
Therefore, the correct answer is option c) -1/3.
