Question

The point at which the line 2x+y=8 intersect the x-axis at

Answer 1

given : 2x+y=8

● when x=0

• 2 (0)+y=8
• 0+y=8

》 y=8

x=0,y=8

●when x=1

• 2 (1)+y=8
• 2+y=8
• y=8-2=6

》y=6

x=1 , y=6

●when x=2

• 2 (2)+y=8
• 4+y= 8
• y=8-4

》y=4

x= 2 , y =4

●when x=3

• 2 (3)+y=8
• 6+y=8
• y=8-6

》y=2

x=3, y=2

●when x=4

• 2 (4)+y=8
• 8+y=8
• y=8-8=0

》y=0

x = 4 , y= 0

=> the x-axis intersect at (4,0)..

hope it may help you ☺☺...
