Chapter 4: Q. 4.19 (page 436)

Use the graph of $y = 3 x - 1$ to decide whether each ordered pair is:
• a solution to the equation.
• on the line.
$ⓐ (0, - 1) ⓑ (2, 5)$

Short Answer

Expert verified

(a) The point $(0, - 1) and (2, 5)$ is a solution.

(b)

Step by step solution

Step 1. Given information

Use the graph of $y = 3 x - 1$ to decide whether each ordered pair is:

• a solution to the equation.

• on the line.

$ⓐ (0, - 1) ⓑ (2, 5)$

Part (a) Step 1. Substitute the x- and y- values into the equation to check if the ordered pair is a solution to the equation.

The given equation is $y = 3 x - 1$

Part (a) Step 2. The first number of the coordinate pair is the x-coordinate, and the second number is the y-coordinate.

$(0, - 1) (2, 5) y = 3 x - 1 y = 3 x - 1 - 1 = 3 \times 0 - 1 5 = 3 \times 2 - 1 - 1 = 0 - 1 5 = 6 - 1 - 1 = - 1 5 = 5 (0, - 1) is a solution . (2, 5) is a solution .$

Part (b) Step 1. Plot the points ⓐ (0,−1) ⓑ (2,5)
