A curve is a line that continuously changes direction, rather than going in a straight line. It can be created by connecting a series of points on a graph or by using a mathematical equation.
The x-axis is the horizontal line on a graph, typically running from left to right. It is used to represent the independent variable or input of a function.
A curve is a type of line that changes direction, while a line is a straight path connecting two points. A curve may also have multiple points and bends, while a line only has two points.
To plot a curve on a graph, you can either use a set of data points or a mathematical equation. For data points, you would plot each point on the graph and then connect them with a smooth line. For a mathematical equation, you would use the equation to calculate the y-coordinate for a given x-value, and then plot those points and connect them with a smooth line.
The slope of a line is the measure of how steep it is. On a graph, it is represented by the change in y-values over the change in x-values. The x-axis represents the independent variable, so the slope of a line can change as the x-value changes.
