A linear function h models a relationship in which the dependent variable decreases 2 units for every 3 units the independent variable increases. Graph h when h (0) = 2. Then identify the slope, y-intercept, and x-intercept of the graph.

    y-intercept is (0,2)

    slope is - 2/3

    x-intercept is (3,0)

    Step-by-step explanation:

    h is linear fn

    so y=h (x) = mx+C

    y-intercept=h (0) = 2=C

    the dependent variable decreases 2 units for every 3 units the independent variable increases

    so slope=independent var/dependent var=-2/3

    y=-2/3x+2

    x-intercept=h (x) = 0

    0=-2/3x+2

    2/3x=2

    x=3

    Slope=-2/3, y-intercept=2, x-intercept=3

    Step-by-step explanation:

    Let the independent variable be x and dependent variable be y

    y=h (x)

    h is a linear function so it is represented in the general form of y=mx+c where

    m is slope and c is the y-intercept.

    Given "the dependent variable decreases 2 units for every 3 units the independent variable increases."

    When x increases by 3, y decreases by 2

    So the slope = rate of change of y / rate of change of x = - 2/3

    Given h (0) = 2, h (0) = m (0) + c=2

    c=2

    Combining slope and y-intercept, y=-2/3*x+2

    x-intercept is when y=0

    0=-2/3*x+2

    2/3*x=2

    x=2*3/2=3

    x-intercept=3
