Question

find k if B (k,-5) , C (1,2) and slope of the is 7

Answer 1

Given that,

Point B = (k,-5) and point C = (1,2) and the slope is 7.

To find,

The value of k.

Solution,

If a line passes through two points, then the slope of the line is given by :

$m=\dfrac{y_2-y_1}{x_2-x_1}$

The slope of line B(k,-5) and C(1, 2) is

$7=\dfrac{2-(-5)}{1-k}\\\\7=\dfrac{7}{1-k}\\\\1-k=1\\\\k=0$

So, the value of k is 0.
