Answer:
the length of side AC is 4 units
Completed question;
What is the length of side AC as shown on the coordinate plane? With coordinates (-2,1) (-2,-3)
Step-by-step explanation:
Given;
A = (-2,1)
B = (-2,-3)
The length L between two points with coordinates (x1,y1) and (x2,y2) can be written as;
L = √((x2 - x1)^2 + (y2 - y1)^2)
Substituting the given values;
L = √((-2--2)^2 + (-3 -1)^2)
L = √(0 + 16)
L = √16
L = 4
the length of side AC is 4 units
