it's fine as written!   i mean can you draw the picture of the line with slope -2 and passing through the point (1,2)

anonymous · Answer

i tried to draw it for you above.

anonymous · Answer

equation of the line having slope  m and passing through (x1,y1) is given by 
y-y1=m(x-x1)

triciaal · Answer

not exactly your slope is positive

anonymous · Answer

woops. let me fix it real quick

triciaal · Answer

point slope formula y-y1 = m(x - x1) where (x1,  y1 ) is given m slope and (x,y) any point on the line
