Question

If the slope of the line joining the point B(k, -5) and P(1, 2) is 7,then complete the following activity to find the value of k

Answer 1

Answer:

answer = - 7

Step-by-step explanation:

slope = y2 - y1 /x2 - x1

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

7 = 2 + 5 / 1 - k

7 = 7 / 1 - k

7( 1 - k ) = 7

7 - 7k = 7

- 7k = 7 -7

- 7 k = 0

k = -7

Answer 2

Answer:

K= 0

Step-by-step explanation:

Given that slope of the line joining the point

B(k, -5) and P(1, 2) is 7

using the formula for slope

(y 2-y 1)/(x2-x1)

we get,

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

7/(1-K)=7

7/7= (1-K)

Therefore,

1-K= 1

K = 0
