What is the slope of the line that is parallel with #y=-2x+1#?

Answer 1

Kennedy Adams

#m = -2#

Because this equation is already in slope-intercept form we can take the slope directly from this equation.

The slope-intercept form of a linear equation is:

#y = color(red)(m)x + color(blue)(b)#

Where #color(red)(m)# is the slope and #color(blue)(b# is the y-intercept value.

Therefore, for the equation in this problem the slope is:

#color(red)(m = -2)#

Because a line parallel to this line will have, by definition the same slope, the slope of a parallel line will also be:

#color(red)(m = -2)#

The slope of any line parallel to the line ( y = -2x + 1 ) is -2.

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.
