Answer:
105
Step-by-step explanation:
Slope formula
y2-y1/x2-x1
1 = x1
-7 = y1
3 = x2
-21 = y2
Plug in the given values into their corresponding spot in the formula:
-21 - (-7) / 3 - 1
-21 - (-7) is the same as -21 + 7
-21 + 7 is the same as 7 - 21
7 - 21 = -14
3 - 1 = 2
-14/2
-14 divided by 2 = -7
The slope is -7
Answer:

Given:
S(-3, 10)
T(-2, 3)
Required:
ST
SOLUTION:
Use the distance formula, , to find ST.
Where,
Answer:
2nd option
Step-by-step explanation:
The exponential function is of the form
y = a
Use the points on the graph to find values of a and b
Using (0, 0.5 ) , then
0.5 = a ( = 1 ) , so
a = 0.5 =
y =
Using (1, 1 )
1 = ( multiply both sides by 2 )
2 = b
Then
y = ← exponential function representing graph
