Draw the graphs of the pair of equations x + 2y = 5 and 2x - 3y = – 4. Find the point of intersection of these lines. Also find the points where the lines meet the x-axis.
Answers
ANSWER : the point of intersection is (1,2)
STEP BY STEP EXPLANATION:
x + 2y = 5
x = 5 - 2y ---(1)
when y = 1 , then x = 3
when y = 2 , then x = 1
when y = 3 , then x = -1
when y = 4 , then x = -3
x 3 1 -1 -3
y 1 2 3 4
( x,y) ( 3,1 ) ( 1,2 ) ( -1,3) ( -3,4)
2x - 3y = -4
2x = -4 +3y
x = -4+3y/2
when y = 2 , then x = 1
when y = 4 , then x = 4
when y = 6 , then x = 7
when y = 8 , then x = 10
x 1 4 7 10
y 2 4 6 8
(x,y) (1,2) (4,4) (7,6) (10,8)
sorrrrrrrrrryyyyyyyyy friend I can unable to draw graph
because here graph is not present
