  1. you have to get y by itself and go from there..

    my school doesn't start 'til tues. so i'm not wasting my brain cells.

    good luck.  


  2. y intercept = (0,-7)

    the slope(gradient)= 0.2

  3. I did this last year. K for y intercept you set x equal to 0 and solve. Sooo...

    9(0)-5y=35.

    9 cancels out

    -5y=35

    Divide by -5 to each side, you get -7.

    So that would be (0,7) for the Y intercept.

    I am not sure for the slope. Its like here in my head but I cant think of it! Sorry

  4. First you have to get the equation in slope intercept form

    y=mx+b

    SO:  y=9/5x+7

    so slope is 9/5 and the y intercept is 7
