Algebra HELP :]?

For questions 1-2, identify the slope and y-intercept of each equation.

1.)y=3/4x-3

a) m=3; b=-3/4

b)m= -3;b=3/4

c)m=3/4;b=-3

d)m= -3/4;b=3

2.)y=-2x

a)m=0;b= -2

b)m= -2;b=0

c)m= -1;b=2

d)m=2;b= -1

3.)m= -3/5,b= -4

a)y= -4x-3/5

b.)y=-3/5x-4

c.)y=4x-3/5

d)y=3/5x-4

thank you soooooooooooooooo much!

    Use y=mx+b formula

    ---------------

    m=slope

    b=y-intercept

    1) y=3/4x-3

    m= 3/4

    b= -3 C

    2) y= -2x

    m=-2

    b=0 B

    What about #3? Anyways there it is..

    3) m=-3/5

    y= -3/5x-4

    b=-4 B

  • y = mx +b where m=slope and b=y-intercept

    1. y=3/4x-3 m= 3/4 b= -3 C

    2. y= -2x m=-2 b=0 B

    3. m=-3/5 b=-4 B

    y= -3/5x-4

    the slope is the coefficient in front of x and the y-intercept is your b

    y=mx+b

    1.) c

    2.) b

    3.) b

    use y= mx+b formula

    1) is c

    2) is b

    3) is b

    by the way I have never seen this kind of easy math problem!
