Question

solve the system graphically x-2y=6 3x+2y=-6

Answer 1

Answer:

here you go love

Step-by-step explanation:

hese are linear equations ie. straight lines.

when these lines intersect with the y-axis then x-coordinate = 0

let x = 0 in 3x - 2y = 6 → 0 - 2y = 6 → y = -3 hence point ( 0 , -3 )

when these lines intersect with the x-axis then y-coordinate = 0

let y = 0 in 3x - 2y = 6 → 3x - 0 = 6 → x = 2 hence point ( 2 , 0 )

plot ( 0 , -3 ) and ( 2 , 0) on squared paper and you have the line with equation 3x - 2y = 6

Similarly for x + y =2

let x = 0 →y = 2 hence point (0 , 2 )

let y = 0 → x = 2 hence point 2 , 0 )

now plot ( 0 , 2 ) and (2 , 0 ) on the same graph as 3x - 2y = 6 and where the 2 lines intersect is the solution to the system of equations.

Answer 2

Answer:

x-2y=6

take x=0 , so 0-2y=6 so y=-3

similarly take different values of x to get the values of y in both the equations .

then draw a graph of x axis and y axis then plot the values of x and y and join them .
