Which corrects Indira's first error? Indira should have substituted B(-6,1) - B'(-3+a,-2+ b) = B(-6,1) in Step 1. O Indira should have written the equations -6+ a=-3 and 1+0=-2 in Step 2. O Indira should have solved the equations to find that a = -8 and --2 in Step 3. Indira should have written the translation rule (x, y) →(x-4y+4) in Step 4.
