Answer:
y = 4/3x - 2, B is your answer
Step-by-step explanation:
Y intercept is the number next to slope(b).
The co efficient of x will be your slope so therefore the co efficient of x will be 4/3
y is always there because it will always be the dependent variable on the left side.
For this case we have that by definition, the equation of a line in the slope-intersection form is:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Where:
m: It is the slope
b: It is the cut point with the y axis
The slope is: ![m = \frac {2} {5}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%20%7B2%7D%20%7B5%7D)
Thus, the equation is of the form:
![y = \frac {2} {5} x + b](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%20%7B2%7D%20%7B5%7D%20x%20%2B%20b)
We substitute the given point and find "b":
![-5 = \frac {2} {5} (- 5) + b\\-5 = -2 + b\\-5 + 2 = b\\b = -3](https://tex.z-dn.net/?f=-5%20%3D%20%5Cfrac%20%7B2%7D%20%7B5%7D%20%28-%205%29%20%2B%20b%5C%5C-5%20%3D%20-2%20%2B%20b%5C%5C-5%20%2B%202%20%3D%20b%5C%5Cb%20%3D%20-3)
Finally, the equation is:
![y = \frac {2} {5} x-3](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%20%7B2%7D%20%7B5%7D%20x-3)
Answer:
![y = \frac {2} {5} x-3](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%20%7B2%7D%20%7B5%7D%20x-3)
Answer:
10
Step-by-step explanation:
12-6+4
5 quarters =1.25$
15$÷1.25$=12
then 15$ in quaters would weigh 12 ounces
