Answer:

x + 3y + 11 = 0  is the  required equation.

Step-by-step explanation:

Here the given points are A( -2,-3) and B(4,-5)

Now, slope of the equation = \frac{y_2 - y_1}{x_2 - x_1}  = \frac{-5 -(-3))}{4-(-2)}   = \frac{-2}{6}   =-\frac{1}{3}

Hence, the slope of the equation is m = (-1/3)

Now, by POINT SLOPE FORMULA:

The equation of a line with slope m and point (x0, y0) is given as

(y - y0) = m (x -x0)

So, here the equation of line with (4, -5) is

y - (-5) = -\frac{1}{3}  (x - 4)  \implies  3( y +5) = -x + 4

or, 3y + 15 + x-4 = 0

or, x + 3y + 11 = 0

⇒ x + 3y + 11 = 0 is the  required equation.

An item is regularly priced at $45 . it is on sale for 60% off the regular price. how much (in dollars) is discounted from the r
wariber [46]
The discount is 60% of regular price, or we can write it as
discount = 60% × regular price

input the numbers
discount = 60% × regular price
discount = 60% × 45
discount = 60/100 × 45
discount = 2,700/100
discount = 27

The answer is $27

How many centimeter squares would be wrapped around this rectangular prism?
denis23 [38]
You haven't told us whether the rectangular prism is the size of a pack of gum or more like the size of a cruise ship.

Whatever size it is, here's the number of centimeter squares you need to cover the whole outside of it:

(2 x length x width) + (2 x length x height) + (2 x width x height)

with all measurements made in centimeters.
