y = 17 x - 17

$y = 17 x - 17$ ,

(1, 0)

$(1, 0)$

Step 1

Insert the values of

x = 1

$x = 1$ and

y = 0

$y = 0$ into the equation to find if the ordered pair is a solution.

0 = 17 (1) - 17

$0 = 17 (1) - 17$

Step 2

Simplify

17 (1) - 17

$17 (1) - 17$ .

Step 2.1

Multiply

17

$17$ by

1

$1$ .

0 = 17 - 17

$0 = 17 - 17$

Step 2.2

Subtract

17

$17$ from

17

$17$ .

0 = 0

$0 = 0$

0 = 0

$0 = 0$

Step 3

Since

0 = 0

$0 = 0$ , the equation will always be true.

Always true

Step 4

Since the equation is always true when the values are used, the ordered pair is a solution.

The ordered pair is a solution to the equation.
