    y = 4x + 10 y = 1/4 x + 5/2 y = -4x - 6 y = – 1/4 x + 3/2

    that is the change of y, over the change of x

    so type the equation using \[\frac {\Delta y} {\Delta x}\]

    yup! that 's correct, now fill in \[\frac {\Delta y} {\Delta x}\]

    okay, put the answer you got for y, in the \[\Delta y\] and then what you got for x in the \[\Delta x\]

    i would say that 2 is my x and 6 is my y but im assuming that isn't correct
