Answer:
f(–5, –3) = –2 This is because the y2-y12/ x2 - x1 = -3-0/-5-0 keeps the formula and keeps the gradient positive as both are negative when only one coordinate is given (sae formula when two or three coordinates are given then we do for each if they are both negative they stay positive) the gradient is 3/5 we then deduct but ore importantly see the relationship up or down y-x = -3 - 5 = -2 so in result f(–5, –3) = –2 as we are aware this is negative points upon graph with a positive slope due to point being in 3rd quadrant
Step-by-step explanation:
f(–3) = –5 f(–3, –5) = –8 f(–5) = –3 f(–5, –3) = –2
