Incorrect. The y-intercept occurs where $\displaystyle{x}={0}\usepackage{cmbright}\Huge\$ . Substitute this value into $\displaystyle{4}{x}-{9}{y}={36}\usepackage{cmbright}\Huge\$ to get $\displaystyle{4}{\left({0}\right)}-{9}{y}={36}\usepackage{cmbright}\Huge\$ . Solve for y. The correct answer is $\displaystyle-{4}\usepackage{cmbright}\Huge\$ .
