As written here, both choices B and C represent proportional relationships:
... B. y = 12x
... C. y = 3x
_____
One key to a proportional relationship is that when one variable is zero, so is the other. This will not be the case for selections A and D.
The perimeter is 18 sq cm.
2(4) + 2(5)
8 + 10 = 18.
Answer:
y =
x + 8
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 =
, then
y =
x + c ← is the partial equation
to find c substitute (- 4, 5 ) into the partial equation
5 = - 3 + c ⇒ c = 5 + 3 = 8
y =
x + 8 ← equation of line
