Question

What is the equation of a line that has a slope of 2 and passes through the point (2, 3)?



y = 2x - 4



y = x + 2



y = 2x + 1



y = 3x - 1



y = 2x - 1

Answer 1

The answer is y = 2x - 1.

Answer 2

as the slope is 2 it will contain '2x'.  and the point (2,3)  which means x =2 when y = 3 fits the equation y = 2x - 1.

So its the last choice.
