Question

Which expression can be used to find the slope of a line containing the points (–3, 2) and (7, –1)

Answer 1

---------------------HEY DEAR--------------------------

HERE IS YOUR ANSWER..................

*****************************************************************

IF YOU NEED TO FIND THE SLOPE OF LINE AND TWO POINTS ARE GIVEN SUCH AS:

P1 (x , y) and P2 (z , h)

then slope of line = ( h - y)/ (z - x)

so, apply this formula here also

slope of line = (-1-2)/(7- {-3})

                       => (-3)/(10)

HENCE,

SLOPE OF LINE IS (-3)/10

Answer 2

slope
$= \frac{y2 - y1}{x2 - x1?}$
