 y = - 4x + - 8 is equation of slope-intercept form.

What is in slope-intercept form?

  • Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form.
  • Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.

the equation of slope - intercept form

                               y = mx + c

( -1 , -4 ) is point shown in graph

            slope = -y/x

                     = - ( -4)/-1  = 4/-1 = -4

             - 4 = -4 * - 1 + c

            - 4 = 4 + c

            c = - 4 - 4 = - 8

put value of c in the equation of slope - intercept form

             y = - 4x + - 8

Suppose xy > 0. Describe the points whose coordinates are solutions to the inequality.
Elan Coil [88]

The solutions fo the inequality are all the points (x, y) that meet these 3 conditions.

  • x ≠ 0
  • y ≠ 0
  • Sign(x) =sign(y)

<h3>Which points are solutions of the inequality?</h3>

We want to find points of the form (x, y) that are solutions of the inequality:

x*y > 0

Clearly x and y must be different than zero.

So, for example if x = -1, y can be any negative number, for example y= -3

x*y > 0

(-1)*(-3) > 0

3 > 0

This is true.

Now if x  = 1, y must be positive. LEt's take y = 103, then:

x*y > 0

1*103 > 0

103 > 0

Then we have 3 conditions:

  • x ≠ 0
  • y ≠ 0
  • Sign(x) =sign(y)

The solutions fo the inequality are all the points (x, y) that meet these 3 conditions.

Ben owns a townhome valued at $195,000, but still owes $120,000 on the loan. Ben has $5,000 in savings and a balance of $1,400 o
IRISSAK [1]

Answer:

c $99,400

Step-by-step explanation:

$195,00-$120,000=$75,000

$75,000+$5,000+$1,400=81,400

$81,400+$38,000-$20,000=$99,400

Solve: 3n - 6 = -8(6 +5n)<br> and explain how to solve it
hjlf

Answer:

Step-by-step explanation:

First use distributive property: a(b + c) = a*b + a*c

3n - 6 = -8(6 + 5n)

3n - 6 = 6 * (-8) + 5n *(-8)

3n - 6 = -48 - 40n

Now add 40n to both sides

3n - 6 + 40n = -48 - 40n + 40n

43n - 6 = -48

Now add 6 to both sides

43n - 6 + 6 = -48 + 6

           43n = -42

               n = -42 /43

Determine whether the two triangles are similar. PLEASE HELP!!
zvonat [6]

I think that it is C: PQR~XY by AA because there are only two angles that you are given ;the boxes represent 90, so each box has 90 and 62.
