The equation of a line in slope-intercept form, is:
[tex]y=mx+b[/tex]Where the coefficient of x, m, is the slope of the line, and the constant term b is the y-intercept.
By comparing this equation with the given one:
[tex]y=3x+5[/tex]notice that the coefficient of x is 3, which is the slope of the line.
Therefore, the slope of the line is 3.
