The rule of a function is:
You CANNOT have one x-value with multiple different y values in the same function. You can however have different x values with the same y value.
Also for reference: independent means x value and dependent means y- value.

The first answer is not a function because as you can see there is one x-value with multiple y values.

second answer IS a function because as I said before you can have different x values with the same y value

third answer is a function again because you can have different x values with same y value

number four isn't a function bc again the -2 x value has 2 different y Values.

Write in slope intercept form, then convert to standard form Slope=1, y-intercept=-3​
Viktor [21]

Slope = 1

y-intercept = -3, which can be expressed as (0,-3).

y - y_1 = m(x - x_1)

y -(-3) = 1(x - 0)

y + 3 = x

The slope-intercept form is

y = x - 3.

The standard form is Ax + By = C.

y = x - 3

3 = x - y

Done.
