Question

Determine k if 2 is the slope of the line through 2,5 and k,3 points​

Answer 1

Solution :-

• Generally , Formula for finding slope of the line is

$m = \frac{y2 - y1}{x2 - x1}$

• Here 'm' is slope

• Y is ordinate and x is absicssa

Now let's find the value of k by substituting the given values.

$2= \frac{3 - 5}{k - 2}$

$- 2 = 2k - 4$

$2k = 2$

$k = 1$

Note :-

• Two non-vertical lines are perpendicular if the product of their slopes is -1
