Question

Find the slope of the line passing through the points (-2.6) and (4.8).

​

Answer 1

Step-by-step explanation:

Let points be A(−2,6),B(4,8),C(8,12) and D(x,24)

If two lines are perpendicular, then product of their slope is −1

So, Slope of AB× Slope of CD=−1        ......(1)

We know that slope of a line through the points (x1,y1),(x2,y2) is m=x2−x1y2−y1

Slope of line AB passing through A(−2,6) and B(4,8) is

=4−(−2)8−6=4+28−6=62=31

Slope of line CD passing through C(8,12) and D(x,4) is

=x−824−12=x−812

From (1)

Slope of AB×Slope of CD=−1

⇒31×
