Hello there! you can use the expression \frac{ y_{1}-y_{2}}{x_{1}-x_{2} }!

To find slope, subtract the y values over the x values.

In this case:

2 - - 1 / - 3 - 7

3 / -10

So, -3/10 would be the slope of these points.

Hope this helps, have a great day!

Which equation can be used to find the volume of this solid?
Zina [86]

Answer:

V = StartFraction 7 times 6 over 2 EndFraction times 8

Step-by-step explanation:

Volume of a triangular prism is expressed as V = Base area × Height

Base area = area of the triangle = 1/2 × base × height

If the triangular base has a base of 7 inches and height of 6 inches.

The height of the prism is 8 inches.

Base area = 1/2 × 7 × 6

Base area = (7×6)/2

Height = 8

V = (7×6)/2 × 8

The right option is V = StartFraction 7 times 6 over 2 EndFraction times 8

nataly862011 [7]

The question is incomplete. The complete question is :

Carl and Sure are planning to buy a new home. They will both retire in 16 years and do not want to have a house payment at that time. Which offer should they choose?

Offer 1                                           Offer 2                                      

Rate: 7%                                         Rate: 6%                                                      

Time(years): 30                            Time (years): 25

Loan Amount: $200,000             Loan Amount: $200,000  

Monthly Payment: $1,330.60       Monthly Payment: $1,288.60

Total Financed:$479,017.80         Total Financed: $386,580.84

Offer 3

Rate: 5%

Time (years): 15

Loan Amount: $200,000

Monthly Payment: $1581.59

Total Financed: $284,685.71

Solution :

It is given in the question that Carl and Sue are planning to purchase a new house for them. Both of them are going to retire after 16 years from now and they do not want to have any house loan to pay at their retirement time.

So from the offers, Carl and Sue should take the Offer 3 to buy a home for them. This is because rate of interest for the loan amount is less as compared to the other two offers and also loan will be completed within 15 years from now. So they will not have any loan payment at their retirement period.

Therefore, they should choose Offer 3.
