What is the independent variable in the equation y = −5x + 2?

The independent variable in the equation y = -5x + 2 is x.

For the equation y = 3x + 1 and the input value 2, what would be the output?

To find the output value (y) for the given input value (x = 2), we substitute x = 2 into the equation y = 3x + 1:

y = 3(2) + 1

y = 6 + 1

y = 7

Therefore, the output (y) for the input value x = 2 is 7.

In the equation y = -5x + 2, the independent variable is x.
