Find the slope of the line.
A coordinate grid is shown with the x-axis between negative 4 and 4 with interval marks representing one unit, and the y-axis between negative 3 and 5 with interval marks representing one unit. A line is drawn connecting the points left-parenthesis 1 comma negative 2 right-parenthesis and left-parenthesis 3 comma 2 right-parenthesis.
A. –2
B. 2
C. –one-half
D. one-half
We can use the slope formula, which is:
slope = (change in y)/(change in x)
To find the change in y, we subtract the y-coordinate of the first point from the y-coordinate of the second point:
2 - (-2) = 4
To find the change in x, we subtract the x-coordinate of the first point from the x-coordinate of the second point:
3 - 1 = 2
Therefore, the slope is:
slope = 4/2 = 2
The answer is (B).
To find the slope of a line, we can use the formula:
slope = (change in y) / (change in x)
Using the given points (1, -2) and (3, 2), we can calculate the change in y and change in x as follows:
change in y = 2 - (-2) = 4
change in x = 3 - 1 = 2
Now, we can substitute these values into the slope formula:
slope = 4 / 2 = 2
Therefore, the slope of the line is 2.
The correct answer is B. 2.
To find the slope of a line, you can use the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of two points on the line.
In this case, the coordinates of the two points on the line are (1, -2) and (3, 2).
Substituting these values into the formula, we get:
m = (2 - (-2)) / (3 - 1)
= (2 + 2) / (3 - 1)
= 4 / 2
= 2
Therefore, the slope of the line is 2.
The correct answer is B. 2.
