Write the equation of the line that is parallel to the graph of y=-4x-9 and whose y intercept is 3

1 answer:

8 0

Y = -4x - 9
The new line has the same slope as the one above, that is - 4
A y intercept means the point (in this case) is 0,3 [The x value is 3]

y = -4x + b Now use (0,3)
3 = 0 + b
b = 3

y = - 4x + 3 is the line you want.

Well 1/3 for savings means that you save 1/3*4500 or 1500 dollars.
You then have $3000 left. Of this if you spend 50% on food, you spend 0.5*3000 or 1500 dollars on food.
