Answer:
Birthdays are a special time of year.
For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the equation that models the problem:

From here, we clear the value of x.
We multiply both sides of the equation by 2:

We subtract 30 on both sides of the equation:

Answer:
The value of the unknown number is given by:

The graph of the line y = -6 is a horizontal line which passes through the y axis at -6. On the other hand, the graph of the equation, x = 1/6 is a vertical line that passes through the x-axis at 1/6. The intersection of these lines is at a point that is expressed as (1/6, -6).
Answer:

Step-by-step explanation:
step 1
Find the slope
we have
(0,-6) and (1,4)
The slope is equal to

step 2
Find the equation of the line in slope intercept form
The equation of the line in slope intercept form is

we have

-----> y-intercept (given value in the table)
substitute
