Answer:
1.y= -2x+3 slope -2
2. y= -4/5x-6 slope -4/5
3. y= 1/3x=4 slope 1/3
4. y= x+8 slope 1
5. y= 4x slope 4
6. y= 3/2x+7 slope 3/2
7. y= 3/2x+5 slope 3/2
8. y= -1/5x-3 slope -1/5
Step-by-step explanation:
move variable to the right
change the signs
divide both sides
reorder the terms
So I think you should set up an equation like this: 14.95x+16.88y=131.18 , x+y=8
so x=8-y, plug this into the original equation:
14.95(8-y)+16.88y=131.18
Evaluate: 119.60-14.95y+16.88y=131.18
Combine like terms: 119.60+1.93y=131.18
Subtract 119.60 from both sides. You get: 1.93y=11.58
Divide both sides by 1.93. You get y=6
Plug into second equation: x+y=8 ---> x+6=8 and solve for x. x=2
