Assuming the question is referencing only straight line type graphs (equation).
There would my an infinite number of equations because there is an infinite count of different slopes.
Let m be the gradient (slope)
Let the given point be point 1 P 1 ( x 1 , y 1 )
Let any point i be P i ( x i , y i )
m = y i - y 1 x i - x 1
m = y i - ( - 1 ) x i - 0 y + 1 x - 0
