If, y = 0
Then,
4x + 3*0 = 24
4x = 24-0
x = 24/4
x = 6
If, y = 4
Then,
4x + 3*4 = 24
4x = 24-12
4x = 12
x = 3
If, y = 8
Then,
4x + 3*8 = 24
4x = 24-24
x = 0/4
x = 0
So the points of graph,
x | 6 | 3 | 0 |
y | 0 | 4 | 8 |
1. Coordinates of the points where the line intersects at x-axis =
(6,0)
Coordinates of the points where the line intersects at y-axis =
(0,8)
2. Area of triangle formed =
1/2 (base*height)
1/2(6*8)
1/2(48)
= 24 square units.
