Question

solve the linear system below by graphing

Answer 1

plot the two lines in a graph paper.
The point of intersection of the two lines will be the solution.

Answer 2

do i turn the 5/4 and 1/4 into a decimal.

Answer 3

put x = 0 then find y
and then put y = 0 and find x
with the two points draw the line

Answer 4

do that for both ?

Answer 5

yes

Answer 6

okay so for the first equation the coordinates are (-2.4,8)

Answer 7

and for the second its 4,0

Answer 8

for the first equation the coordinates are (0,3) and (-2.4,0) through which the line will pass

Answer 9

okay so when i graph it will you check it?

Answer 10

yes

Answer 11

okay 2nd equation is 4,0

Answer 12

yes that's correct

find another point by putting x =0

Answer 13

0,4 ?

Answer 14

when you put x = 0 in the second equation then y = -1
so the other point through which the line will pass = (0,-1)

Answer 15

okay let me show you what i have

Answer 16

??

Answer 17

yes that's correct. and from the point of intersection you can get the solution

Answer 18

-4.5, -2

Answer 19

is that the solution?

Answer 20

you are very close draw the graph neatly and you will get the accurate solution

Answer 21

i thought it was graphed neatly

Answer 22

okay i see. its just -4,-2

Answer 23

use a graphing calculator to get the accurate solution

Answer 24

i dont have a graphing calculator

Answer 25

yes that's the accurate answer
well done

Answer 26

thank you :)
