Question

The pair of points (6, y) and (10, –1) lie on a line with slope one quarter. what is the value of y? (1 point)a. –5

Answer 1

The slope of this connecting line segment is
         -1 - y        1     -(1+y) 
m = ---------- = ----- = --------
         10-6          4        4

Thus, 4 = -4(1+y), or 4 = -4 - 4y, or -8 = - 4y.    y = 2 (answer)
