To find solutions from graphs, look for the point where the two graphs cross one another. This is the solution point. For example, the solution for the graphs \(y = x + 1\) and \(x + y = 3\) is the ...
A straight line drawn on a grid can be described by a rule connecting the x and y coordinates of every point on the line. This is known as the equation of the line. The equation of any straight line ...
