Question

The graph of the equation y=12x−3 Determine the value of y for the point (4, y).

Answer 1

`y=45`

Explanation:

`y=12x-3`

`y=12(4)-3`

`y=45`

Answer 2

y = 45

Explanation:

Given that the x- coordinate of the point on the line is x = 4

To find the corresponding y- coordinate, substitute x = 4 into the equation.

y = 12x - 3 = (12 × 4) - 3 = 48 - 3 = 45

Thus the point is (4, 45 )
