Parallel lines have the same slope. This means that they will never intersect each other. The only thing that is different is their b value (the constant). So we first have to figure out what the slope is for line B; and we will find the slope of line B because the slope of line B is equal to the slope of line A.
To find the slope of a line, we must use the following equation: y2-y1/x2-x1. This may seem difficult at first but it really isn’t. All you have to do is find two points that at are on the line of line A. Two points are (0,0) and (1,2). You can now use the forumla I’ve written down. x1 is 0, y1 is 0, x2 is 1, y2 is 2. Now we do the following:
(2-0/1-0) = 2/1; 2. This means that the slope is 2. We already know what b is (the constant) because the coordinate (0,-3) is already there. Which means the answer to your question is : 2x-3
