    If a line has a slope of -2/5 and passes through the points (3,7), write an equation for this line in slope intercept form

    you want to use the point-slope equation:\[y-y _{1}=m(x-x _{1})\] next you plug in your values and you get y-7=-2/5(x-3).

    distribute -2/5 and add 7 to both sides and you get y= -2/5x + 6/5 +7

    then just add 6/5 and 7 and your final answer will be y= -2/5x + 8.2. you can leave that in fraction form if you want

    After I distribute it'll be y-7=-2/5x+6/5

    yes, you distribute then add 7 to both sides

    I think it'll be y-29/5=-2/5z

    in slope intercept form you want y to be isolated

    i cant subtract fractions in my calculator

    after you distributed to get \[y -7=\frac{ -2 }{ 5 }x +\frac{ 6 }{ 5 }\] use your calculator to add 7 to 6/5 and that should be your answer

    I got y=-2/5x+41/5
