3. When making crystal light, Maria uses 2 packets to make 6 quarts. If Maria is making a large
amount, how many packets are needed to make
312 quarts?

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

m∠a is 90°

m∠b is 40°
