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
Answer:
y =
Step-by-step explanation:
Given y is inversely proportional to x² then the equation relating them is
y = ← k is the constant of proportion
To find k use an ordered pair from the table
Using x = 3 when y = 1 , then
1 = =
( multiply both sides by 9 )
9 = k
y = ← equation of proportion
