What is the slope of the line passing through the following points: # (1,4), (-2,-5) #?

Answer 1

Kennedy Adams

#"slope "=3#

#"to calculate the slope m use the "color(blue)"gradient formula"#

#•color(white)(x)m=(y_2-y_1)/(x_2-x_1)#

#"let "(x_1,y_1)=(1,4)" and "(x_2,y_2)=(-2,-5)#

#rArrm=(-5-4)/(-2-1)=(-9)/(-3)=3#

#m=3#

We know that ,the slope of the line passing through #A(x_1,y_1)and B(x_2,y_2) #, is #m=(y_2-y_1)/(x_2-x_1) #, Here,#A(1,4)andB(-2,-5)# #:.m=(-5-4)/(-2-1)=(-9)/(-3)=3#

To find the slope of the line passing through the points (1,4) and (-2,-5), you can use the formula:

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

Substitute the coordinates into the formula:

[ \text{slope} = \frac{-5 - 4}{-2 - 1} ]

[ \text{slope} = \frac{-9}{-3} ]

[ \text{slope} = 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.
