**-4x + y = -6**1. Solve for y:**2y = 2x – 6**2. Solve for y:**6x + 2y = 18**3. Solve for y:**6x – 3y = -24**4. Solve for y:**3x – 4y = -12**5. Solve for y:**1. Find the point of intersection:**y = 3x-4 y = -3x+2**2. Find the point of intersection:**y = 4x-1 y = -x+4**1. Writeyour system of equations:**Andrew’s Gym has a $99 activation fee and costs $35 per month. Demetri’s Gym has a $75 activation fee and costs $39.99 per month.**2. Writeyour system of equations:**Dimitriwent to Five Guys for lunch. He bought two hot dogs and three burgers for $14. Eric also went to Five Guys for lunch. He bought four hot dogs and seven burgers for $36.**3. Writeyour system of equations:**Sheyenne went to the Rodeo. She paid a $40 admission fee and $2 per ride. Heather went to the State Fair instead. She paid a $30 admission fee and $4 per ride.**4. Writeyour system of equations:**Michael went to Dunkin Donuts. He bought 6 donuts and 8 breakfast burritos. He spent $9. Mario also went to Dunkin Donuts. He bought 12 donuts and 3 breakfast burritos. He spent $8.25.**Now Put it All Together…**Michael went to Dunkin Donuts. He bought 6 donuts and 8 breakfast burritos. He spent $9. Mario also went to Dunkin Donuts. He bought 12 donuts and 3 breakfast burritos. He spent $8.25. How much does one donut cost? How much does one breakfast burrito cost? Steps: • Write your equations. (What do your variables stand for?) • Solve for y if you have to. • Graph. • Find the intersection. • Answer the question(s). (Cost/Quantity/Best Deal/When same cost?)**1. Graphing by HAND**Put your calculator aside. Graph this equation: y = 2x + 1**2. Graphing by HAND**Put your calculator aside. Graph this equation: y = 2x – 1**3. Graphing by HAND**Put your calculator aside. Graph this equation: y = ½ x + 1**4. Graphing by HAND**Put your calculator aside. Graph this equation: y = ½ x – 1**5. Graphing by HAND**Put your calculator aside. Graph this equation: y = -½ x + 1**6. Graphing by HAND**Put your calculator aside. Graph this equation: y = -½ x – 1
