The pair of points (6,y) and (10,-1) lie on a line with slope 1/4. What is the value of y?
A. -5
B. -2
C. 2
d.5
The formula for finding the slope between two points (x1, y1) and (x2, y2) is given by:
slope = (y2 - y1) / (x2 - x1)
We can plug in the values from the given points:
1/4 = (-1 - y) / (10 - 6)
Now, we can solve for y:
1/4 = (-1 - y) / 4
1 = -1 - y
1 + 1 = -y
2 = -y
y = -2
Therefore, the value of y is -2.
The answer is B. -2.
