The equation y = mx + b shows a straight line in what’s called slope-intercept form. Here, m is the slope, which tells you how steep the line is, and b is the y-intercept, or the point where the line crosses the y-axis. This equation lets you find the value of y for any value […]

The x and y axis are part of the Cartesian coordinate system. The system uses a Cartesian plane to uniquely specify a point by using a pair of real numbers called coordinates. The coordinates are signed distances from two fixed perpendicular lines called coordinate lines. So, the x and y-axis are the coordinate lines on […]
