Answer:
= ± 5
Step-by-step explanation:
(
)² = 25 ( take square root of both sides )
= ± ![\sqrt{25}](https://tex.z-dn.net/?f=%5Csqrt%7B25%7D)
= ± 5
Answer:
y = -
x + 3
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (- 9, 6)
m =
=
= -
, hence
y = -
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 9, 6), then
6 = 3 + c ⇒ c = 6 - 3 = 3
y = -
x + 3 ← in slope- intercept form
You can solve an easy equation in your head by using the multiplication table.
