Which transformation of a figure on a coordinate grid preserves congruence?
A (x, y) → (-0.5x, 0.5y)
B (x, y) + (2x, -2y)
C (x, y) → (3x, 3y)
D (x, y) → (-y), -X)

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form. −three fourthsx + y = 10 3x − 4y = −40 y = three fourthsx + 12 y = three fourthsx + 10

Solve each equation using the quadratic formula. find the exact solutions. 6n^2 + 4n - 11
