find the slope through the points (12, -18), (11,12)
find the slope through the points (-18, -20), (-18, -15)
find the x and y intercepts: 4x + y = 5
find the x and y intercepts: y = 5x - 4
write the equation of the line with a slope of zero and the point (3,4)?
what is the slope of the line x = 1?

QUESTION 1

We want to find the slope through the points (12,-18), (11,12).

We use the slope formula,

We substitute the points to get,

The slope is -30.

QUESTION 2.

We want to find the slope through the points (-18, -20), (-18, -15).

We use the slope formula again to obtain,

We simplify to get;

Division by zero means the slope is not defined.

QUESTION 3

The given equation is 4x + y = 5.

At x-intercept, y=0.

We put y=0 into the equation to get,

The x-intercept is

To find the y-intercept,we substitute x=0 into the equation to get,

The y-intercept is (0,5)

QUESTION 4.

The given equation is

To find the y-intercept put x=0 into the equation.

(0,-4)

To find the x-intercept, put y=0,

QUESTION 5

To find the equation of a line given the slope m, and a point

we use the formula,

The given line has slope zero and passes through

(3,4)

The equation is

Question 6

The given equation is

This is the equation of a line that is parallel to the y-axis.

The slope of all lines parallel to the x-axis is undefined.

The slope of x=1 is not defined.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
