Question

which among the following lie on the graph of the equation 2x-y= -2​

Answer 1

Answer:

Answer

If (3,4) lies in the equation 3y=ax+7, then the must satisfy the equation of the line.

Thus, 3(4)=a(3)+7

⇒12=3a+7

⇒a=

Answer 2

given,

2x-y= -2​

Solution:

$2x-y=2\\\mathrm{Add\:}y\mathrm{\:to\:both\:sides}\\2x-y+y=-2+y\\2x=-2+y\\\mathrm{Divide\:both\:sides\:by\:}2\\\frac{2x}{2}=-\frac{2}{2}+\frac{y}{2}\\x=\frac{-2+y}{2}$
