Question

Find the gradient of line AB if A is (3,4) and B is (4,9) Explain​

Answer 1

Answer:
`\frac{5}1}` or 5

Explanation:

Gradient =
`\frac{y_(2)-y_(1)} {x_(2)-x_(1)}\\` where;

`(x_(1),y_(1) )` is the first point, that is A in this question and

`(x_(2) ,y_(2) )`is the second point, that is B in this question.
Therefore,
`y_(2) -y_(1)`=5

`x_(2)- x_(1)`=1

So, the gradient =
`(5)/(1)` or 5
