Answer:
A
Step-by-step explanation:
For equation 5x - 2y = 2.4
the constant can be solve by converting the equation to a point slope form
equation of a line. It is in the form y = mx + b
Dividing the whole equation
by -2
<span>Y = 2.5x – 1.2 so the
constant is 1.2</span>
Answer: the y-coordinate that completes the point is 5.
Explanation:
An ordered pair (x, y) indicates the x-and-y coordinates of a general point, where x is the input value of a function and y is the output value.
The output value is y = f(x) and must be found applying the rule (function) to the given input value.
In this case the rulte is f(x) = - 3x + 2, and the input value, x, is - 1 (the first value of the ordered pair).
This is the mathematical procedure:
- x = - 1
- f(x) = f (-1) = -3 (-1) + 2 = 3 + 2 = 5.
