Answer:
y = 2x - 3
Step-by-step explanation:
We are asked to find the equation of a straight line
Step 1: find the slope
( 2 , 1) ( 5 , 7)
x_1 = 2
y_1 = 1
x_2 = 5
y_2 = 7
Insert the values into the equation
m = (y_2 - y_1 )/ (x_2 - x _1)
m = (7 - 1 )/ (5 - 2)
m = 6/3
= 2
Step 2: substitute m into the equation
y = mx + c
y = 2x + c
Step 3 : sub any of the two points given into the equation
Let's use ( 2, 1)
x = 2
y = 1
y = 2x + c.
1 = 2(2) + c
1 = 4 + c
c = 1 - 4
c = -3
Step 4: sub c into the equation
y = 2x + c
y = 2x - 3
Answer:

Step-by-step explanation:
- We first compute the ratio of this geometric sequence.

- We simplify the fractions:

- We deduce that it is the common ratio because it is the same between each pair.

- We use the first term and the common ratio to describe the equation:

Answer:
(−∞, ∞) and (−∞, ∞)
Step-by-step explanation:
One example (of many) might be y = 2x. The domain and range of this function are (−∞, ∞) and (−∞, ∞).
