    I learned it in ninth grade and I really don't remember it, but if you show me it, I'm sure I can remember some of it.

    Would the answer be A? -1/4? And could you help me with a similar one just to make sure I did it right?

    \(\bf{y=mx+b}\) m = slope b = y-intercept

    ok so look at the y-intercept at what point does it cross the y-axis?

    At 2?

  33. Mehek14

    so b = 2 \(\bf{y=mx+2}\)

  34. Mehek14
    • one year ago

    so either C or D

  35. Mehek14

    both have the slope 2

    but 1 is -2 one is 2

    I think it's C because it's in the negative

    So, D? Because since the line is going up, it has to be in the positives?
