Answer:
(-4, 2)
Step-by-step explanation:
4x+2y=-12
3x+y=-10
Start by dividing the first equation by 2 to simplify it...
2x+y=-6
Then, subtract -2x from both sides to isolate y...
y=-2x-6
Substitute -2x-6 for y in the second equation...
3x-2x-6=-10
Combine like terms...
x-6=-10
Add 6 to both sides
x-6+6=-10+6
x=-4
Plug -4 in for x to solve for y:
3(-4)+y=-10
-12+y=-10
Add 12 to both sides
-12+12+y=-10+12
y=2
(x,y)=(-4,2)
Answer: y= 1.5x-6
Step-by-step explanation:
1) Find the slope by using change in y over change in x: 
2) Then use the y intercept from the given: -6
3) create an equation in slope intercept form using those factors: y= 1.5x-6

4: b. 3b
5:b. h/g=5/6
Answer:
-5/8
Step-by-step explanation:
So basically with fractions that have different denominators you have to find the GCF (greatest common factor) of both of them, in this case 8 would be a GCF because it you times 4 and 2 you get a whole number of 8. since we found out the GCF we want to set them equal. so take the 1/4 and multiply both the top and bottom by 2, so we end with 2/8. You set the equation back up (-7/8) + (2/8). and combine the numerators -7+2/8 which ends you with with the answer of (-5/8) :)
