Answer:

2x-5

Step-by-step explanation:

First solve for the parenthesis:

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

8x-12-6x+7

Change all minus signs to plus signs:

8x+-12+-6x+7

Now you can use the communicative property to move the terms around:

8x+-6x+-12+7

Then change all "+-" to "-"

8x-6x-12+7

8x-6x=2x

-12+7=-5

2x-5

What is the slope of the line that passes through the points (-4, -1) and (4, 5)?

andreyandreev [35.5K]

Answer:

3/4

Step-by-step explanation:

Since we have two points, we can use the slope formula

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

= ( 5 - -1)/( 4 - -4)

= ( 5+1)/(4+4)

= 6/8

= 3/4
