I want a second opinion please: Graph the equation So, I solved this and I got the equation . This means that the slope of the line is positive, but the answer key shows the graph and it's negative. I think the answer key is wrong because it also has the wrong y-intercept, but I would like a second opinion? Thanks :D
(The answer key graph is below)
