What is the equation of the line in point slope form given a slope of -3 and a point of (-2,-5)?
1 answer:
Answer:
y = -3x - 11
Step-by-step explanation:
Use the given slope and point in the point-slope equation. Solving this will give us the y-intercept equation.
Point-slope formula: y - y = m(x - x)
Plug in the slope and point
y - (-5) = -3(x - (-2))
Subtracting negatives will make them positive. Multiply out the -3 to what is in the parentheses.
y + 5 = -3x - 6
Subtract the 5 from both sides
y = -3x - 11
The equation of the line is y = -3x - 11

Answer:
480
Step-by-step explanation:
(26*-48)+(-48*-36)
-1248 + 1728
480
One half is equal to 3/6.
One third is equal to 2/6.
After removing 600 litres from the tank, there is a decrease from 3/6 to 2/6
3/6-2/6=1/6
600 litres is 1/6 of the tank. Multiply by 6 to get the capacity of a full tank.
600*6=3600
The tank can hold 3600 litres.
