Answer:

a) = Slope of line AB = 1/2

<h2><em><u>Perpendicular = -2</u></em></h2>

<h2>b) <em><u>y = -2x + 6</u></em></h2><h2 />

Step-by-step explanation:

a) When it is perpendicular the answer will be positive if the initial value is negative. If it is a whole number, then the perpendicular number is going to be a fraction. The opposite applies.

b) Slope = -2x

   intercept = ?

y = -2x + b

0 = -6 + b

+6  +6

b = 6

<em><u>y = -2x + 6</u></em>
