Question

what is the slope of the line passing through the points (2 7) and (–1 3)

Answer 1

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 2

We can find slope :
Y2-Y1/X2-X1=m
in there :
Y1=7
Y2=3
X2=-1
X1=2
Now answer ;)
