The graph of (-1,5) passes through and is perpendicular to the line whose equation is x = y

Question

 write an equation in slope-intercept form of a linear function whose graph satisfies the given conditions.

Answer 1

you use the point slope form equation  y-y₁=m(x-x₁₎

y-5=-1(x-(-1)

y-5=-x+1

  +5   +5

y=-x+6 is your answer
