Answer:
slope =
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (18, 26)
m = =
Answer:
Step-by-step explanation:
Given
x² - 3x
To make the expression a perfect square
add ( half the coefficient of the x- term )²
x² + 2( - )x +
, thus
x² - 3x +
= (x - )² ← a perfect square
