Write y= -3/4x - 6 in standard form using integers.
Dafna11 [192]

Answer:

The standard form is  3x+4y=-24

Step-by-step explanation:

The standard form of a linear equation can be written as

ax+by=c

The given equation is

y=-\frac{3}{4}x-6


This equation is in the slope-intercept form.


To rewrite this in standard form, we must multiply through by the least common multiple which is 4.


4y=-3x-24


We now add 3x to both sides of the equation to obtain,

4y+3x=-3x+3x-24


This simplifies to

4y+3x=0-24


Hence the standard form is

3x+4y=-24


The correct answer is A

Please help me i need help!
Lynna [10]

For number 22:

7y=8x-14 ; y=6

Plugging in y, we get:

7*6 = 8x - 14

42 = 8x-14

56 = 8x

x = 7

Comparing answers, x is, indeed 7.
