Answer:

y = 1/2 - 3/2

Step-by-step explanation:

All we need to do is find the y-intercept of the line using the formula for slope intercept form [ y = mx + b ].

-3 = 1/2(-3) + b

-3 = -1.5 + b

-1.5 = b

We can put all the information we know/solved for into the formula.

y = 1/2 - 1.5

Best of Luck!

Answer:

The equation of the line is y = 1/2x - 3/2

Step-by-step explanation:

Plug in point (-3, 3) with slope 1/2 into y = mx + b

-3 = 1/2(-3) + b

-3 = -3/2 + b

+3/2 +3/2

-------------------

-3/2 = b

hence, y = 1/2x - 3/2

A 72,000 gallon water tower is being drained. Two thousand gallons are drained in the first hour. How many hours will it take to

Answer:

To drain the water tower it will take 36 hours.

Step-by-step explanation:

Given:

A 72,000 water tower is being drained, and in an hour 2000 gallons are drained.

Now, to calculate the hours it would take to drain total 72,000 gallons of water, we should divide the gallons of water drained in one hour by total gallons of water in the tower.

Gallons of total water in the tower ÷ Gallons of water drained per hour

$72000\div 2000$

$=\ 36$

Therefore, to drain the water tower it will take 36 hours.

1) Write the equation in slope intercept form if

Slope=3/5 and intercept is 2
y = mx + b
m = 3/5 and b = 2
so

equation in slope intercept
y = 3/5(x) + 2

2. Find the x intercept of the line 5x-2y=10

x intercept when y = 0
so
5x-2y=10
5x-2(0)=10
5x = 10
x = 2

answer
x intercept (2 , 0)

hope it helps
