Answer:
2. Undefined
4. 3/1
Step-by-step explanation:
To solve for y you need to first multiply both sides by 4. This will give you: 4y - 4A / 3 = A + 3B
Next you need to multiply both sides by 3: 4y - 4A = 3A + 9B
Now you need to add 4A to both sides: 4y = 7A + 9B
Now divide both sides by 4:
Y = 7A/4 + 9B/4
A linear function is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. For example, a common equation,
y
=
m
x
+
b
, (namely the slope-intercept form, which we will learn more about later) is a linear function because it meets both criteria with
x
and
y
as variables and
m
and
b
as constants. It is linear: the exponent of the
x
term is a one (first power), and it follows the definition of a function: for each input (
x
) there is exactly one output (
y
). Also, its graph is a straight line.
