The slope and y-intercept are important in graphing and writing the equation of a line. Knowing the slope helps determine the steepness of the line, while the y-intercept helps identify where the line crosses the y-axis. Together, the slope and y-intercept allow us to plot points, draw the line, and write its equation.
Step-by-step explanation:
The slope and y-intercept are important in graphing and writing the equation of a line. The slope (m) determines how steep the line is, while the y-intercept (b) tells us where the line crosses the y-axis. Knowing the slope and y-intercept allows us to plot points on the graph and connect them to draw the line. It also helps us write the equation of the line in the form y = mx + b.
