2. What is the equation of the line parallel to the line whose
1 answer:
Step-by-step explanation:
Paralle lines have the same slope.
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have
Convert to the slope-intercept form:
<em>subtract 9 from both sides</em>
<em>divide both sides by 5</em>
Each of the answers to choose from is not the line equation sought.
The equation:
where <em>b</em> is any real number.

Answer:
C
Step-by-step explanation:
We can use the factored form of the quadratic equation, given by:
Where <em>a</em> is the leading coefficient and <em>p</em> and <em>q</em> are the zeros.
We have zeros <em>x</em> = -2 and <em>x</em> = 3. So, let <em>p</em> = -2 and <em>q</em> = 3:
Next, we are given that our <em>y-</em>intercept is (0, -30).
In other words, when <em>x</em> = 0, <em>y</em> = -30. So:
Solve for <em>a:</em>

<em />
Hence, our factored equation is:
For the standard form, expand:
Simplify:
Distribute:
Our answer is C.
