Finding the Point of Intersection
To find the point of intersection of the line y= 2 and the curve y = x2-x, we can equate the two equations and solve for x.

2 = x2-x

Rearranging the equation, we get:

x2 - x - 2 = 0

This is a quadratic equation that can be solved using the quadratic formula:

x = (-b ± √(b2-4ac))/2a

Plugging in the values, we get:

x = (1 ± √(1+8))/2

x = (1 ± √9)/2

x = (1 ± 3)/2

So, x = -1 or x = 2. Since we are looking for the point of intersection in the first quadrant, we can take x = 2.

Therefore, the point of intersection is (2, 2).

Finding the Slope of the Tangent
To find the slope of the tangent to the curve y = x2-x at the point (2, 2), we need to take the derivative of the function and evaluate it at x = 2.

y = x2-x

dy/dx = 2x-1

At x = 2,

dy/dx = 2(2)-1 = 3

Therefore, the slope of the tangent to the curve y = x2-x at the point (2, 2) is 3.
