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

Answer:

K = -36÷7

Step-by-step explanation:

B ( K , -5 ) = ( x1 , y1 )

C ( 1 , 2 ) = ( x2 , y2 )

Slope of the line = 7

By slope formula

Slope = ( y2 - y1 ) ÷ ( x2 - x1)

7 = ( 2 - 1 ) ÷ ( -5 - K )

7 = 1 ÷ (-5 - K)

(-5-K)7 = 1

-35-7K = 1

-7K = 1 + 35

-7K = 36

K = - 36 ÷ 7
