Answer:

A

Step-by-step explanation:

An ordered pair is a solution if when substituted it makes the equation true. If when you substitute, it does not make the equation true then it is not a solution.

y = -5x - 4

Test:

-52 = -5(10) - 4

-52 = -54 FALSE

-39 = -5(7) - 4

-39 = -39 TRUE

31 = -5(-7) - 4

31 = 31 TRUE

-44 = -5(8) - 4

-44 = -44 TRUE

Y-2 = -3(x + 6), write the equation of the line in slope intercept form.
bija089 [108]

Answer: y=-3x-16

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m is slope and b is y-intercept.

y-2=-3(x+6)        [distribute]

y-2=-3x-18          [add both sides by 2]

y=-3x-16

Now, we see that the equation above matches the slope-intercept form equation. You can see that m=-3 and b=-16.

Elena and Diego each wrote equations to represent these diagrams. For
Tpy6a [65]

Elena is correct

Step-by-step explanation:

This is because a straight angle is always equal to 180 therefore in order to find the value of *w* you would have to add up to angles that are given and subtract them from 180, or in this case add up all the angles including *w* to get 180.

Solve for y in terms of x (rewrite each equation so that it starts with "y=")
White raven [17]

answers:

a. y = -6/5x + 4

b. y = 1/2x - 2

Step-by-step explanation:

a.

5y = 20 - 6x

y = 20/5 - 6/5x

y = -6/5x + 4

b.

-8y = -4x + 16

y = -4/-8x + 16/-8

y = 1/2x -2
