    slant upward and downward

    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.

    'Upward' is in the direction of the top of the page.

    Here the context is about the line and mathematics. I can understand a line slants left to right but upward seems to me not necessary.

    Thank you.

    Re: slant upward and downward

    We read from left to right. When you look at a line from left to right, it will either rise or fall. That is upward or downward.

    On an x-y graph, as the value of x increases, does the y value increase or decrease? If it increases, the slope is positive and it can be said to slant upward.
