Answer:
what do you need help with?
Step-by-step explanation:
M = -2
In perpendicular lines, the slopes are opposite reciprocal. This means you flip the sign (from + to - or from - to +) and flip the numerator and denominator.
So 1/2 becomes negative, and 2/1 = 2
So the slope is -2
Answer: 8f + 24
Explanation: You distribute the outside number to everything in the parentheses
Try to visualize the situation; "A percent multiplied by $45 will be me $27"
$45(x/100)=$27
x/100=27/45
x/100=0.6
x=60%
Therefore, the discount was 60%
