Answer:
3 is the slope and -1 is the y intercept
Step-by-step explanation:
y= -1+3x
Using the slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 3x-1
3 is the slope and -1 is the y intercept
Answer:
the solution is 2x
Step-by-step explanation:
Answer:
can also be expressed as a ratio of two integers.
Step-by-step explanation:
Assume x and y are rational number, then x and y can be written as:
, where a and b are integers and b≠0
, where c and d are integers and d≠0
Then,
=
=
Since the set of integers are closed under multiplication, a*d is also an integer. Similarly b*c is also an integer.
can be expressed as a proportion of two integers, provided that y≠0. From this we can conclude that is a rational number, which concludes that the set of rational numbers are closed under division.
