Slope = (y2 - y1)/(x2 - x1)

= (3/4 - 3) / (2 - 1/2)

= (3/4 - 12/4) / (8/4 - 2/4)

= (-9/4) / (6/4)

= (-9/4) × (4/6)

= -9/6

= - 3/2

Answer

A. -3/2

The answer is A.

We have to find the difference between the cooridants.

1/2-2= -1 1/2 = -3/2

3-3/4 = 2 1/4 = 9/4

We then divide 9/4 by -3/2 (9/4 times -2/3) and we get -18/12 if we divide the top and bottom by 6, we get -3/2.

George wants to know if two pieces of wire are the same length. one wire is 6/8 yard. the other is 3/4 yard. draw a number Line

They are the same length. You need to find the common denominator (8) and multiply both the numerator and denominator on 3/4 to ger 6/8. Than, just draw a numberline comparing the lengths! Hope this helped

Y = 3x + 15 3x + 3y = 9

Zina [86]

Answer:

$\Large\boxed{x=-3}$ $\Large\boxed{y=6}$

Step-by-step explanation:

Given the system of equations

$1)~y=3x+15$

$2)~3x+3y=9$

Divide 3 on both sides of the 2) equation

$3x+3y=9$

$3x\div3+3y\div3=9\div3$

$x+y=3$

Current system

$1)~y=3x+15$

$2)~x+y=3$

Substitute 1) equation into the 2) equation

$x+(3x+15)=3$

Combine like terms

$x+3x+15=3$

$4x+15=3$

Subtract 15 on both sides

$4x+15-15=3-15$

$4x=-12$

Divide 4 on both sides

$4x\div4=-12\div4$

$\Large\boxed{x=-3}$

Substitute the x value into one of the equations to find the y value

$y=3x+15$

$y=3(-3)+15$

$y=-9+15$

$\Large\boxed{y=6}$

Hope this helps!! :)
