Question

2. Find the slope of a line that passes through (-2,-3), and (1, 1) .

a. 1/3
b. 2
c. 2
d. 4/3

Answer 1

@mathmath333 please help

Answer 2

The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.

Answer 4

are you lost or do you understand hartnn's explanation ??

Answer 5

I'm lost still. (I'm an idiot )

Answer 6

:(

Answer 7

\(\large\tt \color{black}{(x_1,y_1)=(-2,-3)}\)

\(\large\tt \color{black}{(x_2,y_2)=(1,1)}\)

Answer 8

you will be using the slope formula :
slope = (y2 - y1) / (x2 - x1)

now you have 2 sets of points
set 1 (x1, y1) and set 2 (x2,y2)

now label your points...
(-2,-3)....x1 = -2 and y1 = -3
(1,1)...x2 = 1 and y2 = 1

now we sub
slope = (1 - (-3) / (1 - (-2).....now solve...but remember that a negative timed=s a negative is a positive.

Can you do it now ?

Answer 9

typo....a negative times a negative is a positive
