$y = 4 x - 3$ , $(4, 2)$

Step 1

Insert the values of $x = 4$ and $y = 2$ into the equation to find if the ordered pair is a solution.

$2 = 4 (4) - 3$

Step 2

Simplify $4 (4) - 3$ .

Step 2.1

Multiply $4$ by $4$ .

$2 = 16 - 3$

Step 2.2

Subtract $3$ from $16$ .

$2 = 13$

Step 3

Since $2 \neq 13$ , there are no solutions.

No solution

Step 4

Since the equation is not true when the values are used, the ordered pair is not a solution.

The ordered pair is not a solution to the equation.
