Question

If the slope of the line joining the points B (K. -5) and
C (1.2) is 7 then find the value of K.​

Answer 1

Step-by-step explanation:

slope=y2-y1/x2-x1

7=2-(-5)/1-k

7=7/1-k

7-7k=7

-7k=0

k=0

Answer 2

Finding the value of k

Step-by-step explanation:

$\ Given \ points:\\\\\ B \ = (k, -5) \ and \ C \ = \ (1,2) \\\\\ find: \ k \ = \ ?\\\\\ m \ = \ \frac{\text{rise}}{\text{run}} \ = \ \frac{y_2 - y_1}{x_2 - x_1}\\\\\ Let \ Line \ is \ BC \ then \\\\\therefore \ Slope (m)\ = 7\\\\7 =\frac {2-(-5)}{1-k}\\\\7 =\frac {2+5}{1-k}\\\\7 =\frac {7}{1-k}\\\\\ 7 (1-k)\ = 7\\\\\ (1-k) = \frac{7}{7}\\\\\ (1-k) = \ 1\\\\1-1\ = \ k \\\\k =0$

$\ The \ value \ of \ k = 0.$
