    x's&y's vallues are (x_1,y_1)(x_2,y_2)now substitute x's and y's

    Slope is 4/3x not 4/5

    no slope is 4/5 x is variable not the slope

    \[\huge\rm y=mx+b\] slope intercept form equation where m is slope and b is y-intercept

    well let's solve for b \[\huge\rm y=mx+B\] substitute m for 4/5 and let (x,y) (4,-3) {you can pick 2nd order pair you will get the same answer) substitute x and y for (4,-3) solve for b

    remember in this order pair (4,-3) first number represent x_coordinate and 2nd number = y-coordinate

    so replace m with 4/5 x with 4 y with -3 then solve for b

    \(\color{blue}{\text{Originally Posted by}}\) @vera_ewing Slope is 4/3x not 4/5 \(\color{blue}{\text{End of Quote}}\) yes i meant to say 4/3 i thought you were including x for slope sorry about that
