There are four consecutive integers where three times the sum of the first and third integers is ten more than the second integer plus four times the largest integer.
Write and solve an algebraic equation to find the largest integer.
3(x + x + 2) = x + 1 + 4(x + 3) + 10
3(2x + 2) = x + 1 + 4x + 12 + 10
6x + 6 = 5x + 23
x = 17
Largest integer = 20

If a line contains the points (4, 7) and (10, -5), write the equation of the line in all three forms
m = (-5 - 7)/(10 - 4) = -12/6 = -2
y - 7 = -2(x - 4) PS
y - 7 = -2x + 8
y = -2x + 15 SI
2x + y = 15
