For this case the generic equation of the line is given by:

Where,
m: slope of the line
b: intersection with the y axis
For this case we have:

Therefore, substituting values in the generic equation we have:

Answer:
The equation of the line is:

option 1
Answer:
2:3
Step-by-step explanation:
Simplica Los dos numeros
6 ÷ 3 = 2
9 ÷ 3 = 3
Y = 13.
Explanation
Replacing the value x with 4 in the function gives that y= 4+9
y= 13
Answer:
The answer to your question is csc Ф = 
Step-by-step explanation:
Process
1.- Determine the sign
We must determine csc Ф in the forth quadrangle, here csc is negative.
2.- Determine the hypotenuse
c² = a² + b²
c² = 3² + (-4)²
c² = 9 + 16
c² = 25
c = 5
3.- Determine csc Ф
csc Ф = 
csc Ф =
= 
The last one because a perpendicular triangle would be drawn from the vertice to the bottom.
