Question

) Solve the following system of linear equations graphically for x and y:

3x+2y=12 ; 5x -2y = 4 .

Find the coordinates of the points where the lines meet the y-axis.​

Answer 1

Write y in term of x
Y= 12-3x/2
X=0,y = 12-3x/2 =12-6x/2 =6
X=2y=12-3x/2 =12-12/2=3
X= 4 , y= 12-3x/ = 12-12 / 2 = 0
Thus the table for the first equation
(3x +2y = 12
