C yes because the ratios are equivalent between each pair of values
Answer:

Step-by-step explanation:
We want to find the distance between (-8,-4) and (2,-9).
We use the distance formula:

We substitute the coordinates to get:

We simplify to obtain:

Add the numbers within the parenthesis to get:

Find the squares of the numbers under the radical


Answer:
slope = - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
Given
5x + y = - 9 ( subtract 5x from both sides )
y = - 5x - 9 ← in slope- intercept form
with slope m = - 5
Parallel lines have equal slopes, thus
The slope of a parallel line to the given equation is m = - 5

Answer: x = -1/2 or x = 3</h3>
===================================================
Explanation:
Set each factor equal to zero and solve for x. This is using the zero product property.
(2x+1)(x-3) = 0
2x+1 = 0 or x-3 = 0
2x = -1 or x = 3
x = -1/2 or x = 3
If you graphed the function, you should see that it crosses the x axis at -1/2 and at 3.
