Question

Write an equation for a line perpendicular to  3y-15x=12 and passing through the point (-10,-2)

anonymous · Answer

rearrange the formula to make y the subject. This allows you to find the slope of the line: $$y=mx+$$ where m is the slope. Then since the line is perpendicular use:$$m_1*m_2=-1$$ to find the slope of the line you need. Then substitue everything into the equation: $$y-y_1=m(x-x_1)$$
