Equation is y=kx. We have four chance to figure out k; hopefully they all give the same result
x=9, y=63, y=kx becomes 63=k(9) so k=63/9=7
x=4, y=28, 28=k(4), k=7
The constant of proportionality is 7; we check 2×7=14, 11×7=77
Answer: k=7, y=7x
Answer: 30
Step-by-step explanation:
5+5 = 10
10 + 10 = 20
10 + 20 = 30

Answer:
When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.

The coordinates are given below as

By applying the rule, we will have

By graphing the triangle, we Will have
