Answer 2

@welshfella @FaiqRaees Hey guys, could you help if you can?

Answer 3

take any value of x and input it in the given equation. Now take those x and y values and plug in the given choices if 0=0 comes then the choice is right

Answer 4

@FaiqRaees But what if the values of x and y haven't been given?

Answer 5

take any value of x like x = 0 now input it in the equation
y^2+7y+1=0 Now work out the value of y. This will be our correct x and y values. Now input them in the given equations

Answer 6

@FaiqRaees How would I work out the value of y here? Is factorization necessary?

Answer 7

Yeah work out the value of y in any way

Answer 8

@FaiqRaees Thank you! :)
