y = 2x - 4
y = 2x + 4
y = 2x - 2
y = 2x + 2
Correct answer is A
The gradient to the curve is found by differentiating the curve equation with respect to x
So dydx 2x - 2
The gradient of the curve is the same with that of the tangent.
At point (2, 0) dydx = 2(2) - 2
= 4 – 2 = 2
The equation of the tangent is given by (y - y1) dydx (x – x1)
At point (x1, y1) = (2, 0)
y - 0 = 2(x - 2)
y = 2x - 4
