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:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
