Answer:
The answers are below bolded just for you.
Step-by-step explanation:
1a) I would choose plan C if I wanted 5 hours of lessons.
1b) I would choose plan B if I wanted 17 hours of lessons.
1c) I would choose plan A if I wanted between 8 and 14 hours of lessons.
2a) Using y=mx+b , the slope formula, we get y=2x+4 (In our case)
2b) The slope would be more steeper and the formula for it would now be y=5x+4. (I can't graph on Brainly)
2c) If the cost of renting shoes went up to 8 instead of 4, the y-intercept would now be 8 and the formula for it would now be y=2x+8. (I can't graph on Brainly)
