you have to write a point slope equation which is formula: y-y1= slope(x-x1)
substitution this equation into your problem
y-7= -4(x-(-2)) ----------> y-7 = -4(x+2)
simplifying this equation
the equation is y=-4x -1
then you stated that (a,-2) then substitution this
-2 = -4x -1
-3 = -4x
x= 3/4
therefore a= 3/4
Answer: Choice D. Segment GN is a median
A median is a segment that goes from a triangle vertex to the midpoint of the opposite side. In this case, point G is the vertex and point N is the midpoint (of side FH). Check out the visual diagram attached below.
note: I'm assuming your teacher meant to say "midpoint of FH" instead of "midpoint of FR" because point R isn't mentioned at all in triangle FGH.
Answer:
best ans is { f(x)| –∞ < f(x) ≤ 4}
Step-by-step explanation:
usually to find the range of a fn, u need to see what the value can be. the graph show only a small range of x values. but u can see f(x) is definitely < 4. so the ans is { f(x)| –∞ < f(x) ≤ 4}
