Correct. The y-intercept of the line is the point on the line corresponding to $\displaystyle{x}={0}.\usepackage{cmbright}\Huge\$ According to the line's equation, if $\displaystyle{x}={0},\usepackage{cmbright}\Huge\$ then $\displaystyle{y}={3}{\left({0}\right)}-{7}=-{7},\usepackage{cmbright}\Huge\$ so the y-intercept is $\displaystyle{\left({0},-{7}\right)}.\usepackage{cmbright}\Huge\$
