Answer:
y = x + 2
Slope = rise / run
= 2 / 2 (or 1 bc 2 divided by 2 is 1)
The plotted point on the x axis is on 2
y = x + 2
Answer:
5) y = 3x + 1
6) For this question, I would just draw a line that is increasing, and then once it reaches 10 mins I would make a steep line going downward. Something like this: /\
7) Yes, Raoul is correct because Function A's initial value is 0 and function B's initial value is 3.
Given:
x, y and z are integers.
To prove:
If 
is even, then at least one of x, y or z is even.
Solution:
We know that,
Product of two odd integers is always odd. ...(i)
Difference of two odd integers is always even. ...(ii)
Sum of an even integer and an odd integer is odd. ...(iii)
Let as assume x, y and z all are odd, then is even.
is always odd. [Using (i)]
is always odd. [Using (i)]
is always even. [Using (ii)]
is always odd. [Using (iii)]
is always odd.
So, out assumption is incorrect.
Thus, at least one of x, y or z is even.
Hence proved.
