An ant walked on the coordinate plane from point A( − 3,1) to point B(1,25) by the shortest path. Find y-coordinate of the point
konstantin123 [22]

Answer:

19

Step-by-step explanation:

The shortest path is a straight line.  The slope of that line is:

m = (25 − 1) / (1 − (-3))

m = 6

The point where the ant intersects the y-axis has an x-coordinate of 0.  The slope between that point, and any other point on the line, is 6.

6 = (y − 1) / (0 − (-3))

y = 19

DedPeter [7]
First you calculate the total cost of the pears:
18,4 pounds x $1,75 = $32,2

Them you add the cost of the pineapple:
$32,2 + $2,89 = $35,09

After this you can divide the total cost (35,09) for 4 friends getting the amount due to each one:
35,09/4 = $8,77
