Question

Tell whether (1,6) is a solution of y = x + 7

Answer 1

(1,6) is also (x,y) so that means y=6 and x=1. The full equation would be 6 = 1 + 7 which is not a solution.

Answer 2

Answer:

no it is not a solution.READ THE WHOLE EXPLANATION! IT WILL HELP WITH THE OTHER PROBLEMS!!!!

Step-by-step explanation:

when something like (1,6) is written consider it as (x,y). in this case, 1 is considered as x, and 6 is considered as y. if you substitute these number for x and x and y, (x =1 and y =6), you'll see that the equation will go from y=x +7, to 6=1+7. Which is not true.
