#-2/7#

Given equation of straight line: #-2x-7y=21#

#y=-2/7x-3#

Comparing above equation with the slope-intercept standard form of straight line: #y=mx+c# we get

#m=-2/7# & #c=-3#

hence, the slope of given line is #m=-2/7#

To find the slope given the equation -2x - 7y = 21, rearrange the equation into slope-intercept form, y = mx + b, where m is the slope. Then, solve for y to isolate the slope.

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.
