M= (y2-y1)/ (x2-x1)

Plug the points in.

-9-6/1-1

-15/0 or -15. The slope of the line is -15.

I hope this helped you!

Brainliest answer would be greatly appreciated!

The formula for slope is (y2 - y1) / (x2 - x1).
Substitute your values, and you get (-9 - 6) / (1 - 1), or -15 / 0
Because anything divided by zero is undefined, The line is vertical, so it has no slope. The answer is undefined

Write an equation of the line with the given information. m. 4. A(-1.-5)

Answer:

An equation of the line with the given information with

m = 4 and point A(-1, -5) is:

$y=4x-1$

Step-by-step explanation:

As the equation of a line in point-slope form is given by:

$y-y_1=m\left(y-x_1\right)$

where m is the slope.

Given:

the slope m = 4

the point A(-1, -5)

Substituting the values in the equation of a line in point-slope form

$y-y_1=m\left(x-x_1\right)$

$y\:-\:\left(-5\right)\:=\:4\:\left(x\:-\:\left(-1\right)\right)$

$y+5=4\left(x+1\right)$

subtract 5 from both the sides

$y+5-5=4\left(x+1\right)-5$

$y=4x-1$

Therefore, an equation of the line with the given information

with m = 4 and point A(-1, -5) is:

$y=4x-1$

Step-by-step explanation:

The x intercept is the point that touches the x axis

The y-intercept is the point that touches the y-axis

So...

The x-intercept = (0, -40)

The y-intercept = (0, 15)
