What is the equation in standard form of the line which passes through (4, -2) and has a slope of -3?

Answer 1

Nathan Axel

The equation of the line passing through #(4, -2)# with a slope of #-3# is #y = -3x +10#.

Using point-slope form, #y - y_1 = m(x-x_1)# where #m# is the slope and #x_1# and #y_1# are a given point on the line.

#y - (-2) = -3(x-4)# #y+2 = -3x +12# #y = -3x+10#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
