Answer: y + 2 =
( x - 4 )
Step-by-step explanation:
The equation of a line in point - slope form is given as ;
y -
= m (x -
)
= 4
= -2
m = 
Substitute the values into the equation , we have
y - (-2) =
( x - 4 )
y + 2 =
( x - 4 )
Which could be written as :
y + 2 = y + 2 =
x + 2
Answer:
Presumably you're solving for x here? Without further information we'll assume that.
With that in mind, x is approximately equal to 0.86 and -0.46
Step-by-step explanation:
Let's start by putting it in the usual ax² + bx + c format.

let's solve it. First we'll multiply both sides by five, making the first term a perfect square:

Now we'll add 11 to both sides:

Which makes the left side a perfect square:

And now we can solve for x:

Note that there's no apparent way of drawing the ± symbol when editing equations, so take that + sign as actually being ±.
That gives us two answers:

Answer:
a. 1
Step-by-step explanation:
Replace 1 with x
2 ( 1 + 1 ) = 1 + 3
2 ( 2 ) = 1 + 3
4 = 1 + 3
4 = 4

Answer:
Graph 4
Step-by-step explanation:
Parallel lines have no solution to the system of equation. Graph 4 is a set of parallel lines, so they will never intersect.
