What is the equation of tangent of parabola where parabola is y^2 = 8x  and slope of tangent = 2 ? 

Option: 1

2x + y + 2 = 0 


Option: 2

2x + y + 1 = 0 


Option: 3

2x - y + 2 =0 


Option: 4

As we have learned

y=mx+c is the tangent to y^{2}=4ax if c = a/m

 

Here a = 2 and m = 2 

Thus 

\\y = mx + a/m \\y = 2x + 2/2\\ y = 2x +1
