Help me fast!! I need to get a 90 on it
QveST [7]

Answer:

-7/2

Step-by-step explanation:

Slope equals rise (vertical or y axis) over run (horizontal or x axis).  So you need to find two points on this line that cross directly where the grid lines cross.  If you look closely, the line seems to cross directly at ( -6, 3 ) and again at ( -4, -4).  So the rise values (y axis) are 3 and -4 which is a total of 7 units apart.

The run values are -6 and -4 which is a total of 2 units apart.

So your slope with be 7/2 but since it slopes downward to the right, it is a negative slope.

The answer would be negative 7/2

Total cost for cookie and lemonade is 1.80. If lemonade costs 1.00 more than the cookie, how much was the lemonade?
Ray Of Light [21]

Answer:

The lemonade costs 1.4.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x is the cost of a cookie.

y is the cost of a lemonade.

Total cost for cookie and lemonade is 1.80.

This means that x + y = 1.8.

As we want y, we have that x = 1.8 - y

Lemonade costs 1.00 more than the cookie?

This means that:

y = x + 1

So

y = 1.8 - y + 1

2y = 2.8

y = \frac{2.8}{2}

y = 1.4

The lemonade costs 1.4.
