Answer:
y = -2x -5
Step-by-step explanation:
The line crosses the y-axis at -5. So, b = -5.
It goes down 2 units for each 1 unit to the right, so has a slope of ...
m = rise/run = -2/1 = -2
__
The slope-intercept form of the equation of a line is ...
y = mx +b where m is the slope and b is the y-intercept
For the slope and y-intercept shown, the equation is ...
y = -2x -5

Ratios don't have to be "per" something, while rates are "per" something.
Ratios compare 2 or more values, as well as rates.
Answer: Last option.
Step-by-step explanation:
Given the equation:

Follow these steps to solve it:
- Subtract the fractions on the left side of the equation:

- Using the Difference of squares formula (
) we can simplify the denominator of the right side of the equation:

- Multiply both sides of the equation by
and simplify:

- Multiply both sides by
:

- Apply Distributive property and simplify:

- Divide both sides of the equation by -6:

- Factor the equation and solve for "m":

In order to verify it, you must substitute
into the equation and solve it:
