Answer:
for the first one i think its true equation
for the second one i think its also true equation
Explanation:
because for the first one if x is 1 and y is -1 then it makes 2
and for the first one if x is 0 and y is 2 that also works
for the second one if x is 1 and y is 2 that works
for the second one of x is 0 and y is 4 that also works
im not sure what linear equation means but hopefully you get a good grade on this
