A.
36
B.
–36
C.
15
D.
–4.4
so you take -10.5+5.3+20.2=??
-10.5+5.3=-5.2
-5.2+20.2=15
Ur Answer Is 15
Did I Help??
Hope I Did!!
Answer:
b + 15
Step-by-step explanation:
Let:

Answer:
y = - 3x - 7
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 ) = (- 2, - 1)
m = = = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, - 1), then
- 1 = 6 + c ⇒ c = - 1 - 6 = - 7
y = - 3x - 7 ← equation in slope- intercept form
