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
I'm not sure if you have done vectors as of yet, but you would first add the x components and y components separately.
x-components: 4 blocks + 5 block = 9 blocks
y-component: 2 blocks + 1 block = 3 blocks
Magnitude of this: √(x₂-x₁)²+(y₂-y₁)²
= √(9)²+(3)²
=√81+9
=9.5 blocks approx
Angle of of the resultant vector;
tanθ=y/x
tanθ=3/9
θ=tan⁻¹(3/9)
θ=18.43 degrees

25% can be translated to .25
So you can do 50 x .25
Understand that decimals are less than whole numbers. That means decimals are only part of a whole number. Which is why if you were to multiple any number with a decimal it is LESS than what you started with.
So when you do 50 x .25 you get, 12.5
