Question

The slope of the line below is -3. Is the coordinates of the labeled point to find a point - slope equation of the line

Answer 1

Point slope form = y - b= m ( x - a )

where y and x stay the same

m is the slope

and (a, b) (any coordinate on the graph)

based on the point (5, -7)

Y - (-7) = -3 (x - 5)

however, the - cancels out the negative 7 making I positive

Y + 7 = -3(x - 5)
