    I don't understand the question fully. What do they want exactly? Is that all it says?

    A relation simply describes a relationship and pairs input values with output values. You can represent a relation in several ways. The snacks were represented as ordered pairs, like (3, pretzels). Let's look at a relation with pairs of numbers, instead of a number and a snack. Select each tab to see four ways this relation can be written. (2, 3), (1, 2), (4, 2), (2, −1), (−2, 1)

    domain = set of x values range = set of y values

    so you just list the x coordinates of each point to get the domain

    hint: each point is of the form (x,y)

    the range is similar, just with the y values

    Identify the slope and y-intercept of the equation. y − 4 = −3x.

    add 4 to both sides to get y = ???

    y − 4 = − 3x +4 +4 y = − 3x + 4

    compare y = -3x + 4 to y = mx+b you'll find that m = -3 and b = 4 m is the slope b is the y-intercept

    since m = -3, the slope is -3 since b = 4, the y-intercept is 4. This is the point (0,4)
