The slope of the line defined by the equation 2x + 3y = 18 is -2/3.

2x + 3y = 18 (divide all terms by 3)

(2x/3) + (3y/3) = 18/3;

2/3x + y = 9;

y = -2/3x + 9

2x + 3y = 18 (divide all terms by 3)

(2x/3) + (3y/3) = 18/3;

2/3x + y = 9;

y = -2/3x + 9

2y + 7 and -4y - 10, y = -3;

2y + 7

= 2(-3) + 7

= -6 + 7

= 1;

-4y - 10

= -4(-3) - 10

= 12 - 10

= 2

Answers are 1 and 2.

2y + 7

= 2(-3) + 7

= -6 + 7

= 1;

-4y - 10

= -4(-3) - 10

= 12 - 10

= 2

Answers are 1 and 2.

D. 3 **Weegy:** If a translation is defined by (x, y) (x - 2, y + 3), the image of the preimage point is (-4, 7). Hope this helps (More)

The slope of the line defined by the equation 3x - y = 0 is 3.

3x - y = 0 (divide all terms by -1)

-3x + y = 0;

y = 3x

The slope of the line defined by the equation 3x - y = 0 is 3.

3x - y = 0 (divide all terms by -1)

-3x + y = 0;

y = 3x

x + y = 4, then x = 4 - y

2x + 3y = 2 (4 - y) + 3y = 0

Simplify the equation we get y = -8

so x = 4 - y = 12

2x + 3y = 2 (4 - y) + 3y = 0

Simplify the equation we get y = -8

so x = 4 - y = 12
