I'm currently having a problem with this
$$2x – 5y = 10$$
I'm supposed to write given equation in slope-intercept form and identify slope. I did that, but I thought the answer was $5$, but it keeps telling me I'm wrong. Then I did it again, and got an answer of $2.5$ but it keeps telling me I'm wrong, so I'm not sure what I'm doing wrong. If anyone could help, that would be great. :-)
