# LINR 3 | Lesson 4 | Practice

In the Explore you could have found for example the lines $$y = 8$$ and $$x = 5$$, or any other two perpendicular lines through $$(8, 5)$$.

Identify and solve a system defined by the line $$3x+4y=-4$$, and a second line perpendicular to the first whose x intercept is 6.
