When,

$x = 0, y = - 4, (x, y) = (0, - 4) x = 2, y = 0, (x, y) = (2, 0) x = - 1, y = - 6, (x, y) = (- 1, - 6)$

Step by step solution

Given Information .

The given equation is $y = 2 x - 4$ .

Calculation.

The equation is : $y = 2 x - 4$ .

We will put the values of $x$ in the equation to find $y$ and $(x, y)$ .

When, $x = 0,$

$y = 2 (0) - 4$

Therefore, $y = - 4$ and $(x, y) = (0, - 4)$

When, $x = 2,$

$y = 2 (2) - 4$

Therefore, $y = 0$ and $(x, y) = (2, 0)$ .

When, $x = - 1,$

$y = 2 (- 1) - 4$

Therefore, $y = - 6$ and $(x, y) = (- 1, - 6)$ .
