I was gonna answer but I’m not sure and I don’t want u to get it wrong so I’m just not gonna tell u sorry
Answer:
19.1
Step-by-step explanation:
i took the testttttt
Looking at the purple area, we see that 1≤y≤3. So we can immediately reject answers (d), (a).
Since the purple area is to the right of and above the sloping line, we choose answer (c).
The correct answer to the whole problem is (c).
Answer:
find gradient/slope
-8-(-5) / -2-(-1) = -3/-1
= 3
y=3x+c
perpendicular line formula
m1(m2)= -1
(sub in the gradient before)
3(m2)= -1
m2= -1/3 ( perpendicular line gradient)
y=-1/3x+c
(sub in the coordinate)
-5=-1/3(-3/2)+c
-5=1/2+c
-11/2=c (y intercept)
answer: y= -1/3x - 11/2
