4. $7.40 for 5 pounds

Yes it is $1.50 per pound

Step-by-step explanation:

7.40/5=1.50

5/6

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
