Algebra, Word problem.
A student attempted to graph 4x+5y=0 by finding intercepts. She first let x = 0 and found y; then she let y=0 and found x. In both cases, the resulting point was (0,0). She knew that she needed at least two points to graph the line, but was unsure what to do next because finding intercepts gave her only one point. How would you explain to her what to do next?
