The missing value in the table is 15.
Solution:
Ratio of x to y coordinate:
So, the ratios are equivalent ratios.
To find the missing value in the table:
Multiply the x-coordinate by 3, we get the y-coordinate.
x-coordinate = 5
y-coordinate = x-coordinate × 3
= 5 × 3
= 15
Hence the missing value in the table is 15.
