Hello,
a)
the gradient is the slope:
y+2=3(x-0) or y=3x-2
b) slope is -5 (parallele to y=-5x+4)
y+1=-5(x-0) or y=-5x-1
The sequence here start out by adding 3 then 5 then 7
we see an increse of 2 to what we are adding so to get the next one we would add 2 to 7 to get 9 then add that to 22 to get 31
Answer:
what do you mean by models? equations or experiments?
