Answer:
D
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 ) = (- 2, 15) and (x₂, y₂ ) = (1, 6) ← 2 ordered pairs from the table
m = = = = - 3 , then
y = - 3x + c ← is the partial equation
To find c substitute any ordered pair from the table into the partial equation
Using (2, - 3 ) , then
- 3 = - 6 + c ⇒ c = - 3 + 6 = 3
The y- intercept c = 3 → D
Answer:
Graph 1 goes with the equation
Graph 2 goes to the equation y =
Graph 3 goes to the equation y = x + 10
-11 ≤ 6 - 2n - 5
-11 ≤ -2n + 1
-11 (-1) ≤ -2n + 1 (-1)
-12 ≤ -2n
-12/-2 ≤ -2n/-2
6 ≥ n
(remember, you only flip the sign if you are <em>dividing </em>a negative number
6 ≥ n is your answer
