I'm confused on two questions that are kind of similiar:

State the slope and y-intercept of
y= -1/2x
I know the slope is -1/2 but I don't know the y-intercept

State the slope and y-intercept of
y= 3x-4
I know the slope is 3, but I don't know if the y-intercept is 4 or -4.

  • Math - ,

    y-intercept is a point where the graph of a function intersects with the y-axis

    y-intercept is value of y where x=0

    y= -1/2x

    Slope -1/2

    y-intercept y= -1/2*0= -1/0= +/- infinity

    y= 3x-4

    Slope 3

    y-intercept y=3*0-4=0-4= -4

  • Math - ,

    If yor function:
    y= -1/2x

    mean y=(-1/2)*x

    then:

    Slope -1/2

    y-intercept y=(-1/2)*0= 0
