Question

Given that the gradient of a straight line passes through points A (2,9 )and B (3q, 10) is – 4, find the value of q.​

Answer 1

Answer:

We know that the equation of line passing through point (x

0

,y

0

) whose slope is m is

(y−y

0

)=m(x−x

0

)

Thus the equation of line passing through the point (−4,3) whose slope is

2

1

is,

(y−3)=

2

1

(x+4)

⇒2(y−3)=(x+4)

⇒x−2y+10=0

Answer 2

this is the method for this question
