Answer:

Step-by-step explanation:
We have been given that Vladimir is walking down the street at a speed of 4 miles per hour. We are asked to write an for the distance in miles, d, that Vladimir walks over time in hours, t.
We will use rate formula to solve our given problem.


Upon substituting our given information in distance equation, we will get:


Therefore, the equation
represents the distance that Vladimir walks over time in hours.
The last one is no solutions and the first on is <span>infinitely many solutions
and the second one is one solution. I am pretty sure! Hope this helps!</span>
Answer:
y - 5 = -3(x - 12)
General Formulas and Concepts:
<u>Algebra I</u>
Coordinates (x, y)
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
Point (12, 5)
Slope <em>m</em> = -3
<u>Step 2: Write Function</u>
<em>Plug in variables into the general formula.</em>
- Substitute [PSF]: y - 5 = -3(x - 12)
