6. a) Rivka used the last four digits of her
1 answer:
Answer: Her e-mail password is
Step-by-step explanation:
You know that a part of Rivka's e-mail password is formed by the last four digits of her telephone number.
The exercise gives you the last four digits of Rivka's telephone number:
Now, in order to find the other numbers, you need to descompose into its prime factors. Then:
Therefore, based on this, you can determine that her e-mail password is:

Answer:
.
Step-by-step explanation:
The question requires that the equation should be in the slope-intercept form . The
and
in this equation are constants. In particular:
would represent the slope of this line (also known as the gradient of this line,) whereas
would be the
-intercept of this line.
The question states that the slope of this line is . Therefore,
. Thus, the equation for this line should be in the form
.
The value of constant could be found using the other piece of information: the point
is in this line. In other words, the solution
should satisfy the equation
.
Substitute into the equation
and solve for
:
.
.
.
Hence, would be the slope-intercept form of the equation of this line.
