The mass of a cat in grams is greater because in 1 gram=0.001 kilograms
Slope of a line passing through two given points
= (y2-y1)/(x2-x1)
For m=3, and substituting coordinates,
3=(1-y)/(4-1)
solve for y
1-y=3*3=9
y=1-9=-8
Answer: y=-8
That’s a hard one for sure but I would say six
A I believe (sry if I’m wrong)
