Answer:
the domain for this parabola is all real numbers
The equation of the line is 
Explanation:
The equation of the line is perpendicular to
The equation is of the form
where m=-14
<u>Slope:</u>
The slope of the perpendicular line can be determined using the formula,



Thus, the slope of the line is 
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,

Substituting the slope
and the point (2,-4), we get,

Simplifying, we get,



Thus, the equation of the line is 
Answer:
z ≤ 7
Step-by-step explanation:
9x - 7 ≤ 28 + 4x
9x - 4x ≤ 28 + 7
5x ≤ 35
x ≤ 35 / 5
x ≤ 7
