complete the ordered pairs below so they satisfy the equation.
$y = -10x + 18$
complete the following ordered pairs.
$(0,\square)$
$(2,\square)$
$(\square,78)$
(simplify your answers. type an integer or a fraction.)

Explanation:

Step1: Find y when x=0

Substitute $x=0$ into $y=-10x+18$:
$y = -10(0) + 18 = 18$

Step2: Find y when x=2

Substitute $x=2$ into $y=-10x+18$:
$y = -10(2) + 18 = -20 + 18 = -2$

Step3: Find x when y=78

Substitute $y=78$ into $y=-10x+18$, solve for $x$:
$78 = -10x + 18$
$-10x = 78 - 18$
$-10x = 60$
$x = \frac{60}{-10} = -6$

Answer:

$(0, 18)$
$(2, -2)$
$(-6, 78)$
