At the point of intersection of the parabola y = x^2 - 5x + 4 and the line y = 2x - 2, the value of x and y is equal.
So we can equate the two and solve for x.
x^2 - 5x + 4 = 2x - 2
=> x^2 - 7x + 6 = 0
=> x^2 - 6x - x + 6 = 0
=> x(x-6) - 1(x - 6) = 0
=> (x - 1)(x -6) = 0
So we have x = 1 and 6
The value of y for x = 1 is 0 and for x = 6, y = 10.
Therefore the point of intersection are ( 1, 0) and (6, 10)
Given the parabola y= x^2 - 5x + 4 and the line y= 2x-2
We need to find the intersection points of the parabola and the line.
The intersection points are the values of x and y such that:
the parabola y = the line y
==> x^2 - 5x + 4 = 2x -2
We will combine like terms and solve for x.
==> x^2 - 7x + 6 = 0
Now we will factor.
==> (x-6)(x-1) = 0
==> x1= 6 ==> y1= 2*6-2 = 10
==> x2 = 1==> y2= 2*1 -2 = 0
Then we have two intersection points:
The intersection points of the parabola and the line are (6, 10) and (1,0)
