Answer:
-20 = 0
Step-by-step explanation:
-8 (6 + x) + 4 (2x + 7) = 0
-48 - 8x + 8x + 28 = 0
-20 = 0
3.25 is rounded to the nearest thousandth

Answer:

Step-by-step explanation:
Hi there!
Slope intercept form:
where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)
<u>1) Find the slope (m)</u>
where the two given points are
and 
Plug in the given points (2,8),and (8,2)

Therefore, the slope of the line is -1. Plug this into
:

<u>2) Find the y-intercept (b)</u>

Plug in a given point and solve for b

Add 2 to both sides

Therefore, the y-intercept is 10. Plug this back into
:

I hope this helps!
