<PRE><B>Question 205869</B>
A straight line L passes though the point (0,-1) and is parallel to the straight line y=3x+1.
-------------
The slope, m, of the line y=3x+1 is 3.
------------
i. Write down the equation of the straight line L.
Use (always):
y-y1 = m*(x-x1) (x1,y1) is the point (0,-1)
y+1 = 3x
y = 3x-1 is the line L.
ii. Given that L passes through the point (2,b) find the value of b.
y = 3x-1
x = 2
y = 5 = b
