Answer: k ≤ -4 or k ≥
<u>Explanation:</u>
| 3k + 4 | ≥ 8
3k + 4 ≥ 8 or 3k + 4 ≤ -8
<u> -4</u> <u> -4 </u> <u> -4</u> <u>-4 </u>
3k ≥ 4 or 3k ≤ -12
<u>÷3 </u> <u>÷3 </u> <u> ÷3 </u> <u>÷3 </u>
k ≥
or k ≤ -4
The equation of a line that passes thruogh the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
so
passing through (a,b) and having slope of b is
y-b=b(x-a)
