To write the equation of a line, we use the equation: y = mx +b.
m is the slope of the line, which can be calculated using the equation:
m = (y2 - y1)/(x2 - x1)
We can choose any two points on the line to put into this equation. The red dots are at (0,0) and (-6,-2), so we will use those, but you would get the same answer by using any other pair of coordinates on the blue line.
m = (-2 - 0)/(-6 - 0) = 2/6 = 1/3
b is the y-intercept of the line. The y-intercept is the y-coordinate when the line crosses the y-axis. It crosses the y-axis at (0,0), so the y-intercept is 0.
Now, we plug our values back into the full equation to get the equation of the line.
y = mx + b
y = (1/3)x + 0
So the final answer is y = (1/3)x or y = x/3, depending on how you want to write it.

Step-by-step explanation:
<u>Given</u>:
Juan has been saving for a new bike for two months. So far, he has saved $150 for the bike.
The money that he has saved so far is 30% of the cost of the bike.
We need to determine the total cost of the bike.
<u>Total cost of the bike:</u>
Let x denote the total cost of the bike.
The total cost of the bike is given by
![30\% \ of \ x=150](https://tex.z-dn.net/?f=30%5C%25%20%5C%20of%20%5C%20x%3D150)
The value of 30% can be written as ![\frac{30}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B100%7D)
Thus, we get;
![\frac{30}{100} \times x=150](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B100%7D%20%5Ctimes%20x%3D150)
Multiplying both sides by
, we have;
![x=150 \times \frac{100}{30}](https://tex.z-dn.net/?f=x%3D150%20%5Ctimes%20%5Cfrac%7B100%7D%7B30%7D)
Simplifying, we have;
![x=\frac{15000}{30}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B15000%7D%7B30%7D)
![x=500](https://tex.z-dn.net/?f=x%3D500)
Thus, the value of x is 500.
Hence, the total cost of the bike is $500.
