What is the slope of the line described by the equation below y-5=-3(x-17)

Y-5=-3(x-17)
y=-3x+51+5
y=-3x+56

If we have a funtión:
y=mx+b
The slope is "m".
In this case, m=-3

Answer, the slope is "-3".

The equation y - 5 = -3(x-17) is in the form called point-slope form, which is:

y - y₁ = m(x - x₁)

Where m is the slope and (x₁, y₁) is a point on the line.

The slope of y - 5 = -3(x-17) is -3.
