x = -2 2 10 y = 1 2 4 determine the slope of the line
a. 1/4
b. -1/4
c. -4
d. 4
To calculate the slope of the line, we use the formula:
slope = (change in y) / (change in x)
Using the points (x1, y1) = (-2, 1) and (x2, y2) = (10, 4):
change in y = 4 - 1 = 3
change in x = 10 - (-2) = 12
Slope = 3 / 12 = 1/4
Therefore, the correct answer is:
a. 1/4
