Find the point slope equation for the line that passes through the points (1,-9) and (-10,101)
1 answer:
Answer:
( y + 9 ) = -10( x - 1 )
Step-by-step explanation:
First we calculate the slope
Then we choose a point it could be (1,-9) or (-10,101), I choose (1,-9), the slope point form is (y-y1)=m(x-x1)
( y - (-9) ) = -10( x - 1 )
( y + 9 ) = -10( x - 1 )
it could be also...
( y - 101 )= -10( x- (-10) )
( y - 101 ) = -10( x + 10 )

So, if ya wanna solve this question and of course questions alike, ya gotta pay attention to the graph. mean All of these parabolic chart have the domain of R
Step-by-step explanation:
So there ya go
D=R
and now bout the range ya gotta find the vertex, which is:
now pay attention
X=2/–2=–1
y=–(–1)²–2(–1)+3=4
Now the highest point of your parabolic chart is 4 and the lowest point is endless which is (–♾,4]
Well, finally your answer is D
