Answer:
y = - 2x + 13
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 ) = (3, 7) and (x₂, y₂ ) = (5, 3)
m =
=
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 7), then
7 = - 6 + c ⇒ c = 7 + 6 = 13
y = - 2x + 13 ← equation of line
Answer: X - 10 = How many books Carla has
Step-by-step explanation: Carla has 10 FEWER books than Dominic and we will represent Dominic with X we don't know what X is and no matter what the number is Carla always has 10 less so X(Dominic's books) - 10(How many fewer books) = How many books Carla has.
