Answer:
y=2x-2
Step-by-step explanation:
find the slope (m)
m=y2-y1/x2-x1
m=4-(-2)/3-0
m=4+2/3-0
m=6/3
m=2
y-y1=m(x-x1)
y-(-2)=2(x-0)
y+2=2x
y=2x-2
One thing for sure it is not b,d,c its a
Answer:
1) (x + 12)²+(y+6)²= 28
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√28
h=-12
k=-6
;.centre=(-12,-6)
radius =√28 units
2) x²+(y+7)²=15
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√15
h=0
k=-7
;.centre=(0,-7)
radius=√15 units
3) (x + 4)²+(y - 1)² = 4
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√4=2units
h=-4
k=1
;.centre=(-4,1)
radius=√2units
4) (x+3)²+(y-1)²= 8
comparing above equation with(x-h)²+(y-k)²=r²
we get
r=√8=2√2units
h=-3
k=1
;.centre=(-3,1)
radius=2√2units
The value of k so that the two given lines are parallel is; k = 22.5
First, the correct question is;
In line segment geometry;
- The slopes of two or more parallel lines are equal
First, we must determine the slope of the lines by rewriting the equations to resemble the equation of a line in the slope-intercept form; y = mx + c
Therefore, we have;
- y = (k/5)x - 4/5.................eqn(1)
- and y = (9/2)x + 11/2....,........eqn(2)
- Evidently, the slope of the line in equation 2 is; 9/2
.
And since the slope of parallel lines are equal;
By cross product;
k = 22.5

Answer:
Step-by-step explanation:
We can add the same quantity to both sides of the equations, and still have an equivalent equation. Let's add 
to both sides, then sum like terms
(this is the rule that allows us to move items from one side do the other of the equal sign by changing its sign)
At this point we have a solution, let's replace it to verify
