<PRE><B>Question 401850</B>
(1,5) and (-8,9)
Y=mX+b
m=(y2-y1)/(x2-x1)
m=(9-5)/(-8-1)
m=4/-9=-4/9 for the slope.
5=-4/9*1+b
5=-4/9+b
b=5+4/9
b=(45+4)/9
b=49/9 the Y intercept.
Y=-4X/9+49/9
9Y=-4X+49 ANS.
{{{ graph( 300, 200, -6, 5, -10, 10, -4x/9 +49/9) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, -4x/9 +49/9).
