👉 In linear, or linear, graphing, a straight line is drawn from one point to another on a graph. The slope of this line represents how steeply it rises or falls, and the y-intercept (where x=0) indicates where the line crosses the y-axis. For example: - In the equation y = 2x + 3, the slope is 2, meaning as we move up from the origin, the y-coordinate increases by a factor of 2.
