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.
Lo siento, no hago matemáticas por favor hazlo tú mismo. En caso de que no traduzcas esto voy a poner un par de números. 34 es el número para hacer que alguien que habla inglés esto es legítimo. 45 = 28 + x28. Te quiero
The radius is 4.
Find the radius of the circle whose equation is (x + 5)2 + (y + 8)2 = 16
