A: -15/5 degrees Celsius
B: -15/5=3 degree Celsius
every 5 weeks it change -15°c
so each week it changes -3°c
The answer is 6 to your question, but why does my answer have to be at least 20 characters long?
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 )
Here m = - 2 , then
y = - 2x + c ← is the partial equation
To find c substitute (4, 5) into the partial equation
5 = - 8 + c ⇒ c = 5 + 8 = 13
y = - 2x + 13 ← equation of line
