How do you find the slope and y-intercept for the line #y=4#?
Remember the standard linear equation: y=mx+b. The variables 'mx' represent the slope of a linear line meaning in the equation y=4, there is no slope, or a slope of 0. The y-intercept can easily be determined in this equation because the straight line falls on 4, the number equal to y in the equation. Take a look at the graph.
