Here will be references for you: You need to know slope-intercept form. It is that one form where you can easily see slope and \(y\)-intercept. It is \(y=mx+b\) where \(m\) is the slope and \(b\) is the \(y\)-intercept. A line that is perpendicular to another line has a negative reciprocal slope of the other. How do you know the slope of the other? It is in slope-intercept form, so you can look at what must be \(m\); what is multiplying \(x\). So, you can find your slope that way. Then you can use point-slope formula, \(\dfrac{y-y_1}{x-x_1}=m\). You know that your point on the line is \((x_1,\ y_1)\) and you know the slope, \(m\), from finding the negative reciprocal of the other slope. Then solve for \(y\) in that last equation to see the slope-intercept form.
