3. Write the equation of the line that goes through the point (6,5) and is perpendicular to the line y = 3x + 8.
Parallel lines have the same slopes. Perpendicular lines have opposite and reciprocal slopes.
What is the slope of y = 3x + 8? (Hint: You can write the slope as a fraction by putting it over"
m =
Since your line is perpendicular to y = 3x + 8, your slope has the opposite sign and reciprocal (flipt
fraction) slope. m your line =
Use your slope and the given point to solve for "b" and write the equation.
