Answer:
9
Step-by-step explanation:
Calculate the absolute difference of the 2 points, that is
| - 7 - 2 | = | - 9 | = 9 , or
| 2 - (- 7) | = | 2 + 7 | = | 9 | = 9
The answer is -5. Hope it helps.
The equation for working out the slope of a linear line is:
, where x and y are the coordinate pairs.
So just pick two of the purple dots on the graph and fill in the equation.
I'll pick the dot that's (-4, 1) and (4, -7).
Now I just do
, which is just
when simplified.
Answer:
If this is the complete question them the answer is 1250 m²
Step-by-step explanation:
the pool in the drawing is 15x7.5 and the scale is 3/1000 so if the size in the drawing is 3 then the actual is 1000.
x=15*1000/3=5000cm which would be 50m
x=7.5*1000/3=2500cm which is 25m
the actual area of the pool is 50*25=1250 m²
