Question

find the slope of the line that passes through the point (2,-5) and (7, 1).Choose (x1, y1)x1= y1=

Answer 1

To find the slope, you calculate the ratio of change in y-axis values to change in x-axis values.

$\frac{\Delta y}{\Delta x}=\frac{1--5}{7-2}=\frac{6}{5}=m$

Here x1= 2 x2=7 change in x=7-2 =5

and

y1=-5 , y2 = 1 , change in y= 1--5=6

The slope is 6/5
