Question

What is the equation of the line that passes through the point (2, 5) and has a slope of 2?
A) y = 2x + 1
B) y = 2x + 3
C) y = 2x - 8
D) y = 2x - 3

Answer 1

y - 5 = 2(x - 2)

y - 5 = 2x - 4

y = 2x + 1

Answer 2

y = mx+b


5 = (2)(2)+b


5 = 4+b


5-4 = b


1 = b


b = 1


So the equation of the line is y = 2x+1

Answer 3

For this type of question, plug in x( value of 2 in this case ) into the equation and see if the y comes out as 5. Then you look at the slope by seeing the coefficient of x, and if it's 2. A satisfies both conditions, and so it's the answer.
