Question

Wrie down the equation of the line that is parallel to 4x - 2y = 7 and passes through (9, -3) ​

Answer 1

4x-2y =42 is the required equation

Explanation:

given equation is,

4x-2y -7=0---------eqn1

parallel equation of given equation is

4x -2y+k =0-------eqn 2

now passing it through (9,-3), we get,

4×9 + 2×3 +k = 0

or,36+6+k =0

or,42+k =0

or, k= -42

putting the value of k in eqn2

4x-2y - 42=0

4x-2y = 42
