Problem

Ex. 1 Graph the equation $y=2 x+3$

Solution

Step 1 :Choose some values for x and calculate the corresponding values for y. Let's choose x = -2, 0, 2.

Step 2 :Calculate the y values using the equation y = 2x + 3.

Step 3 :y_values = [(-2) * 2 + 3, 0 * 2 + 3, 2 * 2 + 3] = [-1, 3, 7]

Step 4 :Combine the x and y values to form points: (-2, -1), (0, 3), (2, 7)

Step 5 :Plot the points on a coordinate plane and connect them to form a straight line.

Step 6 :\(\boxed{\text{The graph of the equation } y = 2x + 3 \text{ passes through the points } (-2, -1), (0, 3), \text{ and } (2, 7)}\)
