You’re supposed to graph the function. So basically you’ll want to make it so that y=, and then the rest of your formula.
So in this case y=3x+9
Your slope=-2
Which is 2/1 (rise/run)
Your y-int=-1 (which means your graph should touch the -1 on the y-int
So your answer would be A
Answer:
1). x = 14
2). y = 2.4 cm
Step-by-step explanation:
In the diagram ΔNPQ ~ ΔNLM and NL = 3,
1). ∠P ≅ ∠L [All angles of similar triangle are equal in measure]
(3x + 18)° = 60°
3x = 60 - 18
x = 14
2). Since, both the triangles are similar, corresponding sides will be proportional.


y 
y = 2.4 cm
The answer is D, (2,2). A vertex is where a line or curve meets and changes direction.
