Answer:
Step-by-step explanation:
hello :
the general term is : An =A1×r^n when A1 =30 r=1/2
the fourth term is :A4 when n = 4
A4= 30×(1/2)^4 = 30/16 = 15/4
The slope is 2/3 and the y intercept if you need it is -3
Answer:
I say a
Step-by-step explanation:
Is it a rotation 90° a clockwise about the origin?
Answer:
y = -
x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m =
= - 
The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1
y = -
x - 1 ← equation of line
