Question

draw the graph of equation X + 3 Y = 15 find the co-ordinate of point where the graph intersect the x - axis

Answer 1

x+3y=15
x= 15-3y
let the value of y be 3
x=15-3×3
x=15-9
x=6
let the value of y be 4
x= 15-3×4
x=15-12
x=3
let the value of y be 5
x=15-3×5
x=15-15
x=0
then we will plot a graph
it wil cut x axis at 14
and the co ordinate will be (14,0)
