Answer:
A
Step-by-step explanation:
We know that (15, 11) (which means x = 15, y = 11) is a solution to Line Q so therefore:
11 = 4/3 * 15 + (k + 1)
11 = 21 + k
k = -10
-10 = k
y = 4/3x + ( k+1)
We know a point on the line is ( 15,11)
Substitute this point into the equation
11 = 4/3(15) + (k+1)
11 = 20 + k+1
Combine terms
11 = 21+k
Subtract 21 from each side
11-21 = k
