Write an equation for the line, in point-slope form, that passes through the points (-5, 7) and (-4, -3). Use (-5, 7) as the point (x1,y1)

So far I got Y- 7=-1/9(X + -5)

  • Algebra - ,

    (y - Y1)____ (Y2 - Y1)
    --------- = ---------
    (x - X1)____ (X2 - X1)
    means
    (y - 7)/(x+5) = (-3 -7)/(-4 + 5)
    or
    (y - 7)/(x+5) = -10/1 = -10
