Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = =
= -
The y- intercept is where the line crosses the y- axis
The line crosses the y- axis at (0, 3 ) ⇒ b = 3
(b)
y = - x + 3 ← equation of line
Answer:
Step-by-step explanation:
Given is the sequence 3, 8, 13, 18, 23, ….:
We find that this is a geometric sequence with each term added with 5 to the previous term
Hence recursive formula is
Non recursive formula:
iii) Start with 3.
Add 5 and write as 2nd term
Take the resulting term and add 5 and mark as 3rd term
Repeat this m times.
