Vertex is (7,-4) for answer.
Hope this helps. :)
Slope of line
m= (y2-y1)/(x2-x1)
=(-4--6)/(6--2)
=2/8
=1/4
Line in two point form
(y-y1)=m(x-x1)
y--2=(1/4)(x-6)
y+2=(1/4)(x-6)
simplify
4(y+2)=x-6 =>
x-4y-14=0
Alternatively, use the slope intercept form:
y--2=(1/4)(x-6) =>
y=(1/4)x - 3/2-2 =>
y=(1/4)x -7/2
Answer: 4x² -4
Step-by-step explanation:
First, evaluate the exponent you'll get, 
+ 4x² -5 then evaluate to get, 1+ 4x² -5. Next, subtract the numbers, 1 + 4x² -5 then to get, -4 +4x². Lastly, rearrange the terms, -4 +4x² turns into, 4x² -4!
Answer:
0.15
Step-by-step explanation:
Fp: frequency that the pitcher will throw exactly 4 pitches to a batter=15
Fa: frequency that the pitcher will throw any pitches to a batter=15+20+40+15+10=100
P=Fp/Fa=15/100=0.15
