#1) Let's suppose that ax+by = c is the equation of a non-vertical line. Determine the slope of the line:

a.

Slope is Suppose that the vector 3 = a? + b}: is not vertical. Find the slope of this vector. Slope is Use your above answers to find an equation for the line through the point P = (6, 7) perpendicular to the vector 5? + 8}. Hint: Think about the relationship between the slopes of two perpendicular lines. Line is
