Answer:
Find it yourself pay attention in class don’t be lazy asking this website this doesn’t even work if you ask be so don’t be stupid and do it yourself
Step-by-step explanation:DO IT YOURSELF
The y-intercept in the equation in the form y = mx + b is b.
To find the y-intercept in x - y = -1, isolate y on the left-hand side:
x - y = -1
-y = -x - 1
y = x + 1
b in this equation is 1, so the y-intercept is 1.
Hope this helps.
You want to put this in the form (x+b)^2 + c
To do this take half of the coefficient of b from the ordinal form which is 6/2=3 as use this as your new b
This give you (x+3)^2.
If you foil this out you get x^2 +6x +9 so you have added 9 to the original expression so now all you need to do is subtract 9 to keep things balanced
The final expression then is (x+3)^2 -9
<u> So c= -9</u>
Answer:
x=2 and y = 2
Step-by-step explanation:
Im going to use GeoGebra for graphing the 2 lines. I always find it helpful to move y to side of the equation and the rest of the equation to another side. This is the slope intercept equation by the way. We get our equations as y = -2x+6 and y= 2x-2.
You can find that the common point is (2,2) between the lines.
The answer is y-9,27 is 3
