Question

What is the equation of the line that is parallel to y=2x+2 but passes through the point (1,6)

Answer 1

y=2x+4

Explanation:

y=2x+2

Gradient = 2

Gradient of the line passing through point (1,6)

= 2

i.e it is parallel to line y=2x+2.

Equation of the line is given as:

y - 6 = 2(x - 1)

y - 6 = 2x -2

y = 2x -2 + 6

y = 2x + 4
