Answer:
Step-by-step explanation:
*Assuming commas are used for decimals.
<h3><u>Given that:</u></h3>
2.6 kg potatoes = R 13.20
<h3>Using unitary method</h3>
Divide 2.6 to both sides
1 kg potatoes = R 13.20/2.6
1 kg potatoes = R 5.1
Multiply 3.3 to both sides
3.3 kg potatoes = R 5.1 × 3.3
3.3 kg potatoes = R 16.75

To be perpendicular, the slope of the new line has to have the reciprocal of the original slope.
Do this by flipping the slope (ifi t's a whole number make it a fraction) and change the sign.
3 ⇒ -1/3
Input x and y and solve for b.
5 = -1/3(-6) + b
Simplify.
5 = 2 + b
Subtract 2 from both sides.
3 = b
y = -1/3x + 3
