8 and 3

Step-by-step explanation:

Brainliest Please

One example is x = -8, y = -3

Step-by-step explanation:

Lets make a system of equations.

Let x be the first number and y be the second.

x * y = 24

x + y = -11

Solve for x and substitute.

x = 24/y

24/y + y = -11

24 + y^2 = -11y

y^2 + 11y + 24 = 0

Factor.

(y + 8)(y+3) = 0

So one example is x = -8, y = -3

you need to show us the graph.

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
