    • @momigaming8598
      @momigaming8598 4 месяца назад +1

      There's an easier way to find the gradient. Just find two random points on the line, trace where they cut the x and y axis, for example (8,6) and (-7,5) or something idk. Label them as x² y² and x¹ y¹ and put them in the equation y²-y¹/x²-x¹
      And solve it and you got your gradient. Either this is correct or I'm cooked.

      The -9 is the difference between +5 and -4
      He started of with 5 and counted down until he got to -4 the difference was 9 and because he was subtracting its -9

    Does it depend on how you draw the triangle when you’re working out the gradient like it could be the same number but a negative because I may have drawn the rise downward? Does it depend on how you look at it or am I making a mistake ?
