I cannot understand the prepositions upward and downward in "If a line slants upward it has a positive slope and if a line slants downward it has a negative slope."
Another example: "If a line slants upward from left to right, it has a positive slope." Here I can understand "left to right" but "upward" does not make sense to me. Would you explain it?

Thank you.
