Answer:
Option B, y intercept of -4
Step-by-step explanation:
Option A is incorrect because you cannot use the slope because you don't know where or what point to start from.
<em>Option B is correct because the first thing you do is plot the y intercept of -4 and then you find the slope of the line.</em>

Option C is incorrect because you cannot use the slope because you don't know where or what point to start from.
Option D is incorrect because that is the wrong y intercept.
Answer: Option B, y intercept of -4
Undo what has been done to the variable. That means to do the opposite done to the variable.
5x-4=-19
+4=+4
5x=-15
5 is being multiplied to the variable so you divide it from both sides.
x=-3
The linear inequalities shown are...
y> or equal to (1/2)x-1
and
y< -3x+1
Answer:
u = -2, -3/5
General Formulas and Concepts:
<u>Algebra I</u>
- Standard Form: ax² + bx + c = 0
- Factoring
- Finding roots
Step-by-step explanation:
<u>Step 1: Define equation</u>
5u² + 6 = -13u
<u>Step 2: Solve for </u><em><u>u</u></em>
- Rewrite: 5u² + 13u + 6 = 0
- Factor: (u + 2)(5u + 3) = 0
- Find roots: u = -2, -3/5
