Math. HELP!

1. What is an equation for the line with slope 2/3 and y-intercept 9?

2. What is an equation in slope-intercept form for the line that passes through the points (1,-3) and (3,1).

3. For the equation -4y = 8x, what is the constant of variation?

4. Suppose y varies directly with x, and y = 24 when x=8. What is the value of y when x = 10?

Please help, I don't understand any of this?

  1. #1. remember the slope-intercept form?

    y = mx+b

    #2. The slope is (1+3)/(3-1) = 2
    So, the point-slope form is
    y-1 = 2(x-3)
    Now rearrange that into slope-intercept form.

    #3 -4y = 8x
    so, y = -2x

    for the equation y = kx, k is the constant of variation

    #4. y = kx, so y/x = k, a constant. Thus, you want y such that

    y/10 = 24/3

    If you really don't understand any of this, you need to see your teacher, review the text, or google the topic and read the many examples online.
