Final answer:
Given the linear equation y = 3x – 5, the output when the input is -4 is found by substituting -4 into the equation, which produces an output of -17.
Step-by-step explanation:
The student is asking how to find the output of a linear equation given an input value. Specifically, the equation provided is y = 3x – 5, and we are asked to find the output when the input (x) is -4.
To find the output (y), simply substitute -4 into the equation for x and solve:
y = 3(-4) – 5
y = -12 – 5
y = -17
So, the output for an input of -4 is -17.
