Final answer:
The equation of the line passing through the points (-2,3) and (0,3) is y = 3.
Step-by-step explanation:
The equation of the line that passes through the points (-2,3) and (0,3) can be determined using the slope-intercept form of a linear equation, y = mx + b. The slope (m) of the line can be found using the formula m = (y2 - y1) / (x2 - x1), where (x1,y1) and (x2,y2) are the coordinates of the two points. Since both points have the same y-coordinate, the slope is 0. Therefore, the equation of the line is y = 3, or y = 0x + 3.
