2. m= 1/2 b=-2
3 and 4. answered below
5. The point of intersection is where two lines intersect.
Step-by-step explanation:
you have -x+2y=6. finding the slope is very easy, you just have to isolate y.
2y=6+x ---> y = 3+ x/2. The slope would be 1/2 for the first one. the y intercept would be 3.
To graph, there are different ways of doing it. You can do it by finding the y intercept and x intercept, by making a chart and finding plotting points, or you can do it graphing the y intercept and doing rise over run from there.
The
(x-3)^2=(3x+10)*(x-3) so to solve this u can simply take (x-3) over to the other side so it will; look like this
(x-3)^2/(x-3)=3x+10
then it will be x-3=3x+10
-2x=13
x=-13/2 which is -6.5
Answer:
103y/100
Step-by-step explanation:
(2x - 8) - (4x + 8)
first look at the x
2x - 4x = -2x
-2x is left over
then look at the numbers
8 - (-8)
in the case of having two negatives, it becomes positive, and so it is really 8 + 8
8 + 8 = 16
-2x - 16 is your answer
hope this helps
9n = 3n-12
-3n= -3n
6n= -12
divide by 6 = -2 =n
to check.. 9 times -2 = -18 soo.. 3 times -2= -6-12= -18
so it is correct!!
hope it helps :)
