express 3x + 4y = 12 in intercept form represent this line on a graph paper find the area of the triangle formed by this line and the co-ordinate axis graphically and algebraically.

12
3x+4y=12
=>y=-(3/4)x+4 [SLOPE-INTERCEPT FORM]
hence,
angle,= tan^{-1}(-3/4)
= 37°
AND
base, = 4
therefore,
area, 1/2×4×3 = 6
