How do you find the slope of the line passing through (2.5,0), (-3.5,-4)?

Answer 1

#"Slope of the given line is "color(indigo)(2/3)#

#"To find the slope of line passing thru "(2.5,0), (-3.5, -4)#

#Slope " " m = (y_2-y_1) / (x_2 - x_1) = (-4-0) / (-3.5 - 2.5)#

#=> (-4 / -6) = 2/3#

To find the slope of the line passing through (2.5,0) and (-3.5,-4), use the formula for slope:

[ m = \frac{{y_2 - y_1}}{{x_2 - x_1}} ]

Substitute the coordinates into the formula:

[ m = \frac{{-4 - 0}}{{-3.5 - 2.5}} ]

[ m = \frac{{-4}}{{-6}} ]

[ m = \frac{2}{3} ]

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.
