The answer is
<h2>
</h2>
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
where
m is the slope
( x1 , y1) is the point
From the question the point is (-5,-2) and the slope is - 6/5
The equation of the line is
We have the final answer as

One month = 5000
Number of months before the spark plugs need to change :
15000 ÷ 5000 = 3
