Question

Plz help thank you very much!

Answer 1

(1, - 4 )

Explanation:

To find the y- coordinate, substitute x = 1 into the equation

y = (3 × 1) - 7 = 3 - 7 = - 4

Answer 2

The missing value is -4.

Since you already know that x = 1, substitute that into the equation and simplify. y = 3(1) - 7

Anything times 1 equals itself. y = 3 - 7

Subtract. y = -4
