5. Solving Equations by Graphing
Sign In
where m is the slope of the line and b is the y-intercept. Thus, a and c represent the slopes of the lines while b and d represent the y-intercepts. It is given that 0
Now that we have placed the y-intercepts, we can sketch the lines using the slopes. Since a
From the graph, we can see that the lines intersect at a negative x value. Thus, the solution to ax+b=cx+d is negative.
