Answer:

y+2 = -4/5(x-3)

Step-by-step explanation:

The point slope form of a line is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

y - -2 = -4/5(x-3)

y+2 = -4/5(x-3)

Dmitry [639]

Answer:

Option D. 3:1, $120

Step-by-step explanation:        

The complete question in the attached figure    

Part 1) What is the ratio between the amount of money contributed by Anna and the amount contributed by her mother?      

Let    

x -----> the amount of money contributed by Anna      

y ----> the amount of money contributed by her mother    

we know that    

Looking at the table  

The value of x is equal to   x=\$30+\$60+\$90+\$120=\$300  

The value of y is equal to   y=\$10+\$20+\$30+\$40=\$100    

Find the ratio  x/y  

substitute the values  

\frac{x}{y}=\frac{300}{100}=\frac{3}{1}  

Part 2)  What was the total amount saved in April?    

we know that        

To find out the  total amount saved in April, adds Mon's contribution in April plus Anna's contribution in April            

so            

(\$30+\$90)=\$120
