Explain how to graph a linear equation using its slope and y-intercept.

• Draw a curved line using the slope and y-intercept

• Plot the y-intercept on the x-axis and use the slope to find a second point

• Plot the y-intercept on the y-axis and use the slope to find a second point to draw a straight line.

• Use the slope to find the y-intercept and plot it on the x-axis
