For this case we have that by definition, the line equation of the slope-intersection form is given by:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Where:
m: It's the slope
b: It is the cut-off point with the y axis
According to the statement we have:
![m = \frac {1} {2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D)
Thus, the equation is of the form:
![y = \frac {1} {2} x + b](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D%20x%20%2B%20b)
We substitute the given point and find "b":
![-4 = \frac {1} {2} (1) + b\\-4 = \frac {1} {2} + b\\-4- \frac {1} {2} = b\\b = - \frac {9} {2}](https://tex.z-dn.net/?f=-4%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D%20%281%29%20%2B%20b%5C%5C-4%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D%20%2B%20b%5C%5C-4-%20%5Cfrac%20%7B1%7D%20%7B2%7D%20%3D%20b%5C%5Cb%20%3D%20-%20%5Cfrac%20%7B9%7D%20%7B2%7D)
Finally, the equation is of the form:
![y = \frac {1} {2} x- \frac {9} {2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D%20x-%20%5Cfrac%20%7B9%7D%20%7B2%7D)
Answer:
![y = \frac {1} {2} x- \frac {9} {2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%20%7B1%7D%20%7B2%7D%20x-%20%5Cfrac%20%7B9%7D%20%7B2%7D)
Answer:
um i dont know
Step-by-step explanation:
-1.....if the number on the left is smaller than the number on the right change the the number on the right to equal the same on the left then however many numbers down you went make that a negative and that’s your answer
Answer:
Step-by-step explanation:
You basically minus the x's
Then get your equation e.g a +b+c=.....
Then find x on its own e.g 2x=4
X= 2
