The y-coordinate that completes the point exists 5.
<h3>What is an ordered pair?</h3>
An ordered pair (x, y) denotes the x-and-y coordinates of a general point, where x exists the input value of a function and y exists the output value of a function.
The output value exists y = f(x) and must be found using the rule (function) to the given input value.
In this case the rule exists f(x) = - 3x + 2, and the input value, x, exists - 1 (the first value of the ordered pair).
This exists the mathematical procedure:
x = - 1
f(x) = f (-1)
Then substitute the value x = -1 then
f(-1) = -3 (-1) + 2 = 3 + 2 = 5.
Therefore, the correct answer is option b) 5.
