What is the slope of a line with a x-intercept of -3 and a y-intercept of -4?

1 answer:

6 0

The x intercept is -3 so the point (-3,0) is on the line. This point is on the horizontal x axis. The x intercept is always in the form (NUMBER,0) where you replace "NUMBER" with any number you want.

The y intercept is -4 so we know that (0,-4) is also on the line. This is on the vertical y axis. The y intercept is always in the form (0,NUMBER)

Use the slope formula to find the slope of the line through the points (-3,0) and (0,-4)

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

m = (-4-0)/(0-(-3))

m = (-4-0)/(0+3)

m = -4/3

The answer is choice B: -4/3

I have a feeling you mixed up x and y somehow when you got -3/4

Anastasy [175]

Answer:

The value is $x = 3.000 * 10^9 \ grains$

Step-by-step explanation:

From the question we are told that

$1m^3 = 10^6 cm^3$

And that

$3000 \ grains \ of \ sand \ is \ in \ 1cm^3$

So the number of sand grain that is in $1m^3$ is mathematically evaluated as

$x = 3000 * 10^6 \ grains$

=> $x = 3.000 * 10^9 \ grains$

Stella [2.4K]

You would is this case use the perfect square rule. So your would squareroot 9r^2 and 25 to get 3r+5 then you would square this equation to get (3r+5)^2
