For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have the following equation:
So:
, the slope is positive
For the graph, we place the point on the coordinate axis:
We draw the line!
The graphic is attached.
ANswer:
, the slope is positive
Answer:
Roots of the equation are (−3−√7) , (−3+√7)
Step-by-step explanation:
For solving a quadratic equation using completing the square method:
- set the value of 'y' = 0
- add and subtract the square of half of the coefficient of x.
- solve the obtained equation for 'x'
given equation:
y = x^2 - 6x +2
0 = x^2 - 6x + 2
0 = x^2 - 3^2 + 3^2 -6x +2
0 = (x-3)^2 -7
7 = (x-3)^2
± = x-3
± + 3 = x
