Answer:

Step-by-step explanation:
We are given;
A geometric sequence;
-2,10,-50
Required to determine the nth term
The nth term in a geometric sequence is given by the formula;

where
is the first term and r is the common ratio;
In this case;

r = 10 ÷ -2
= -5
Therefore;
To get the nth term in the given geometric sequence we use;

Thus, the nth term is 
Answer:
when they cross u should get a perfect solution of (2,6)
Answer:
-5/4
Step-by-step explanation:
Slope is rise over run which means that the -5 will apply to your y values and the 4 will apply to your x values. This slope would have a point move down 5 units and to the right 4 units to get the location of the next point when going left to right. Because the slope contains a negative, the slope will be angled downward left to right. The negative only applies to the 5.
Slope =(9-7)/(4-3) = 2
equation
y - 7 = 2(x - 3)
y - 7 = 2x - 6
y = 2x + 1 .....this is slope intercept form
2x - y = = -1 .....this is standard form
