Kadesha is simplifying the expression below.
Negative (x minus 3) minus 2 (x minus 1)
She lists the steps that she uses to simplify the expression as follows:
Step 1: Distribute β1 through (x minus 3), and distribute β2 through (x minus 1).
Step 2: Rewrite the expression as Negative x minus 3 minus 2 x minus 2.
Step 3: Combine βx and β2x, and combine β3 and β2.
Step 4: The simplified expression is Negative 3 x minus 5.
In which step did Kadesha make the first error?
She made the first error in Step 1 because only β2 should be distributed through the parentheses.
She made the first error in Step 2 because Step 2 should be Negative x + 3 minus 2 x + 2.
She made the first error in Step 3 because βx and β2x cannot be combined.
She made the first error in Step 4 because the simplified expression is Negative x minus 5.

There is a line with slope 1/a going through the point (a, aΒ²). find the equation of the line perpendicular to this line at this point. (donβt let this problem intimidate you! solve the problem as you would if iβd given you specific values. just use variables instead.)
