Can someone give me the answers to this algebra 2 homework?ill give you all the possible points?

Question

its mainly t because the school year just atarted

and i dont have the right book

and i want to get caught up in my class please help

here it goes

1.a consistent system that has exactly one solution is called_______

2.explain how to identify the solutions of a system from the graphs of the equations in the system

graph the linear system and estimate the solution

(please just help me to the best of your abiltity)

3)y=-3x+2

y=2x-3

4)y=5x+2

y=3x

5)y=-x+3

-x-3y=-1

6)x+2y=2

x-4y=14

7)y+2x-10

x-4y=5

8)-x+6y=-12

x+6y=12

9)y=-3x-2

5x+2y-2

10)y=3x-13

-x-2y=-14

11)x-7y=6

-3x+21y=-18

12)y=4x=3

20x-5y=-15

13)5x-4y=3

3x+2y=15

14)7x=y=-17

3x-10y=24

what is the solution of the problem?

15)-4x-y=2

7x+2y=-5

skip 16

classify the system as consistent and independent,consistent and dependent, or inconsistent

17.y=-1

3x+y=5

18)2x-y=4

x-2y=-1

19)y=3x+2

y=3x-2

20 y=-1

3x+y=-3

Answer 1

Suggest you practice these problems....

Tips:

1.) Graph each equation by picking a value for x and finding y or pick a value for yand find x. Make a table

For example

3.) for equation y=-3x+2   if x=0 y=2 , x=1 y=-1, x=-1 y=5

Tip2: Pick a few easy points to plot then draw the lines; where they intercept or cross that is where they have the same point or solution.

Tip3: To verify the point intersection or the common point, you can substitute one equation into the other equation.

For example if y=-3x+2 and y=2x-3 then

2x-3=-3x+2   rearranging gives

5x= 5         or x=1 and  putting x into y=2x-3 gives y=-1

therefore the point of intersection is (x,y)= (1,-1)

All the rest of the problems are similar. If there is no solution when you substitute one equation for the other, the lines do not meet....Problem 19.) has no common point of intersection.
