Answer:
y= 3x + 19, x E R
Step-by-step explanation:
y - 7 = 3 (x + 4)
(distribute the 3 through the parentheses)
y= 3x + 12 + 7
(add the numbers)
y = 3x + 19
(write the solution/answer Y in parametric form)
y = 3x + 19, x E R
Answer:
Option D
and 
Step-by-step explanation:
step 1
<u>Find the equation of the inequality A</u>
we know that
The solution of the inequality A (dashed line) is the shaded area below the dashed line
The equation of the dashed line is 
therefore
The equation of the inequality A is 
step 2
<u>Find the equation of the inequality B</u>
we know that
The solution of the inequality B (solid line) is the shaded area below the solid line
The equation of the solid line is 
therefore
The equation of the inequality B is 
The system of linear inequalities is
and
