Which equation represents a line that passes through negative 9 comma negative 3 and has a slope of negative 6 ?
Answer
A
y plus 9 is equal to negative 6 times open paren x plus 3 close paren
B
y minus 9 is equal to negative 6 times open paren x minus 3 close paren
C
y plus 3 is equal to negative 6 times open paren x plus 9 close paren
D
y minus 3 is equal to negative 6 times open paren x minus 9 close paren
Explanation
Use point-slope form: y − y₁ = m(x − x₁). With slope −6 and point (−9, −3), this becomes y − (−3) = −6(x − (−9)), or y + 3 = −6(x + 9). That is choice C.
