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 )
To calculate m use the slope formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 6) and (x₂, y₂ ) = (8, 4)
m = 
= - 
, hence
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 4), then
4 = - 
+ c ⇒ c = 4 + = 
y = - x + ← equation of line

Answer:
$60
Step-by-step explanation:
The savings of Andries is $120 and his grandfather offered that he would give 50% of the amount he saved.
50% is actually just half of a given amount. So the short way to do this is just half the saving of Andries.
You can also think of it this way:
So we multiply that to the amount saved to solve for what is 50% of 120.
