The slope-intercept form of a line is $\displaystyle{y}={m}{x}+{b}\usepackage{cmbright}\Huge\$ , where m is equal to the slope of the line and b is equal to the y-intercept. Since $\displaystyle{m}={4}\usepackage{cmbright}\Huge\$ and $\displaystyle{b}=-{6}\usepackage{cmbright}\Huge\$ , the equation of the line is $\displaystyle{y}={4}{x}-{6}\usepackage{cmbright}\Huge\$ .
