Question

solve the system of equations by graphing then classify the system
3x + y = 22
4x + 5y = 22
what is the solution set? select the correct choice below and if necessary fill in the answer box to complete your choice
a. the solution is -----
type an ordered pair
b. there are infinitely many solutions
c. there is no solution

Is the system consistent or inconsistent?

Is the system dependent or independent?

Answer 1

by graphing you arrange it that y= something
so 1st : y=22-3x
2nd: y=(22-4x)/5
now the easiest way of graphing a line is to get 2 points and connect them.
1st x=0 y=22 and x=1 y=19 are 2 points
2nd x=0 y=22/5 and x=1 y=18/5

Answer 2

if they are the same line, than there are infinitely many solutions. If they are parallel than there are no solutions. If they have an intersection than they have a solution (an ordered pair)

Answer 3

Hope you can do it now and it helped.

Answer 4

could you specify the points i need to graph please

Answer 5

(0,22) (1, 19)
and
(0,22/5) (1, 18/5)

first is always the x coordinate, 2nd is the y

Answer 6

Thanks Andras that really helped me out

Answer 7

your welcome

Answer 8

Andras i have to pick from 4 graphs that are already connected with the points could you send a pic of one showing how u graph the points so I can compare with what I have to pick from please
