The inputs to the point-slope formula are
• point: (3, 5)
• slope: -2
_____
In slightly more detail, the point can be considered (h, k) and the slope, m. Then the general form of the point-slope formula is
y -k = m(x -h)
and your "inputs" are k=5, m=-2, h=3.
The output of the point-slope formula is
• y -5 = -2(x -3)
