Step-by-step explanation:

Slope Of A Line=(Y2-Y1/X2-X1)

Given That Slope Of A Line Is 7

∴ 7 = (Y2-Y1/X2-X1)

∴ 7 = [2-(-5)]/(1-k)

∴ 7 = 2+5/1-k

∴ 7(1-k) = 7 ______________(Cross Multiply)

∴ 7-7k = 7

∴ -7k = 7-7

∴ k = 0/-7

∴ k = 0

Answer 2

The value of k is 0.

Step-by-step explanation:

We need to find the value of k, If B(k,-5) C(1, 2) and slope of the line is 7 .

if a line passes through two points, then the slope of the line is

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

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

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

$m=\dfrac{7}{1-k}$

The slope of the line is 7. Substitute m=7 in the above equation.

$7=\dfrac{7}{1-k}$

$7(1-k)=7$

$7-7k=7$

$-7k=0$

$k=0$

Therefore, the value of k is 0.
