Commutative property is one of the basic properties of numbers. Numbers can be added or multiplied in any order because changing the order of the number doesn't change the sum or the product.
The slope-intercept form is
y
=
m
x
+
b
y
=
m
x
+
b
, where
m
m
is the slope and
b
b
is the y-intercept.
y
=
m
x
+
b
y
=
m
x
+
b
Find the values of
m
m
and
b
b
using the form
y
=
m
x
+
b
y
=
m
x
+
b
.
m
=
0.75
m
=
0.75
b
=
0.25
b
=
0.25
The slope of the line is the value of
m
m
, and the y-intercept is the value of
b
b
.
Slope:
0.75
0.75
Y-Intercept:
0.25
Answer: $6.99
Step-by-step explanation: each minute is 20 cents and the connection fee is .99 cents.
30x.20= 6.00
6.00 + .99 = $6.99
