Please help If P(6,-2( Q(-2,8) R(-4,3) and S(-9,y) find y so that line PQ is perpendicular to line RS

Two different linear functions are shown below with two points given from each function. use slope-intercept form or point-slope form to find the equation of each. linear function a points: (–5, –2), (–5, 7) linear function b points: (7, –5), (–2, –5) function a has: the equation of line a is: function b has: the equation of line b is:
