Answer: <em>2x + y = 10</em>
Step-by-step explanation: When we're given a point and a slope, we can use the point-slope formula to write the equation of a line.
The point-slope formula is y - y₁ = m(x - x₁).
Now we can substitute our point and our slope into the formula.
y - 4 = -2(x - 3)
~distribute
y - 4 = -2x + 6
~isolate y
y = -2x + 10
~put into standard form
2x + y = 10
I would say this 7 because when you subtract

Im pretty sure hope it helps
Answer:
C and D
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, - 6) and (x₂, y₂ ) = (9, 3) ← 2 points on the line
m =
=
= 
Using (a, b ) = (9, 3 ) , then
y - 3 =
(x - 9) → C
Using (a, b ) = (- 3, - 6 ), then
y - (- 6) =
(x - (- 3) ) , that is
y + 6 =
(x + 3) → D
