Mike is saving to buy a car. He already has $500 in the bank, and he plans to save $250 each month. This relationship is represented by the equation y=250x+500, where x is the number of months and y is the total money saved.

1. Identify the slope.

2. Explain what the slope means in this problem.

3. Identify the y-intercept.

4. Explain what the y-intercept means in this problem.

First remeber that the standard from of a line is 
Y = Mx + C

anonymous · Answer

1. M is the slope so that is 250

anonymous · Answer

2. slope is a rate of change - so in this equation - he is planning to save at a rate of 250 per month

anonymous · Answer

3. Y intercept are where x = 0 
y = 250(0) +500
y= 500

intercept is (0, 500)

anonymous · Answer

4. y intecerpt is where the lines crosses the y axis.

All about        y =    mx                   +     b
Total payment  = monthly payment   +  deposit
