y=mx+b

find m by taking the  rise/run, between the two points

find b by checking the y-intercept

anonymous · Answer

4 rise 6 run ?

whpalmer4 · Answer

well, if you're counting squares.  except the rise and run have to be figured in the same direction.  you've done one in the opposite order.  As you went 6 squares to the right, the line dropped 4 squares, it didn't rise 4 squares.

whpalmer4 · Answer

it turns out not to matter that you counted squares instead of finding the difference between the coordinates, so long as the squares are, well, square :-)

anonymous · Answer

i counted the sqaures and it was 6,4

whpalmer4 · Answer

no, it's 6, -4.

unklerhaukus · Answer

the two points given are $$(x_1,y_1)=(-3.75,-1.75)\(x_2,y_2)=(-0.75,-3.75)$$


the rise between theses points is      $y_2-y_1$

the run between these points is        $x_2-x_1$
