Question

6. Explain why (4, 1) is not a solution to the equation y=3x + 1.

Answer 1

see explanation

Explanation:

to determine if (4, 1 ) is a solution of the equation, substitute the x and y coordinates into the equation and if both sides are equal then it is a solution.

y = 3(4) + 1 = 12 + 1 = 13 ≠ 1

since y ≠ 13 then (4, 1 ) is not a solution to the equation

Answer 2

x is 4 and y is 1

So we put 3 x 4 + 1

if it's equal 1 (since y is 1)

but in this case it equals 13 so it's wrong
