How do you write the point slope form of the equation given m=-7 and (1,-1)?

1 Answer

See a solution process below:

Explanation:

The point-slope formula states: #(y - color(red)(y_1)) = color(blue)(m)(x - color(red)(x_1))#

Where #color(blue)(m)# is the slope and #(color(red)(x_1, y_1))# is a point the line passes through.

Substituting the slope and values from the point in the problem gives:

#(y - color(red)(-1)) = color(blue)(-7)(x - color(red)(1))#

#(y + color(red)(1)) = color(blue)(-7)(x - color(red)(1))#
