what is answer to y=x-3
what is y=x-3
If this is a question of slope then remembering the formula can help.
y = mx + b
Where "m" is the slope of the line, and "b" is the y-intercept (where the line crosses the y-axis).
So your problem is: y = x - 3.
If there is no coefficient on x then the slope is 1. (for every move to the right (x) you move up one (y)).
The - 3 indicates that this line will go through the y-axis at (0,-3).
Some other points on this line would be (-3,-6); (-6,-9); and (3,0).
