You need to add more context im afriad
Answer:

Step-by-step explanation:
To factor the equation, break it into two binomials which multiply to make the equation. To write these binomials (x+a)(x+b), find factors which multiply to 30 and add to -13 for a and b.
30: 1, 2, 3, 5, 6, 10, 15, 30
-3+-10 = -13

When you write a number in expanded form, you separate the digits based on their place value and turn it into an addition expression. The answer is 30+2+0.0+0.03, or if your teacher doesn't require the extra 0.0, just remove it.
Hope that helped.
The horizontal line has an equation: y = a, where a is any real number.
We know, the line passes through the point (-8, -7) → x = -8, y = -7.
<h3>Answer: y = -7</h3>
