Question

If 3x+7y= 14 express y in terms of x check whether (3 ,-2)is a point on a given line

Answer 1

3x+7y =14
7y= 14-3x
Y= 14-3x/7

Answer 2

Answer:

$y=\frac{14-3x}{7}$

(3 ,-2) is not a point on a given line.

Step-by-step explanation:

Given : $3x+7y=14$

To Find: If 3x+7y= 14 express y in terms of x check whether (3 ,-2)is a point on a given line

Solution:

Equation: $3x+7y=14$

express y in terms of x

$3x+7y=14$

$7y=14-3x$

$y=\frac{14-3x}{7}$

Now, check whether (3 ,-2) is a point on a given line

If the given point satisfy the equation then it lies on the line

$-2=\frac{14-3(3)}{7}$

$-2=\frac{14-9}{7}$

$-2\neq\frac{5}{7}$

Hence (3 ,-2) is not a point on a given line.
