What is the equation of the line that passes through the point 4, -6 and has a slope of -3
zheka24 [161]
Y = mx + b. Use this equation for most linear functions. Enter the information that is given to you.
- 6 =  - 3(4) + b
Multiply the -3 and 4 to get 12.
-6 =  - 12 + b
Now divide the -12 from both sides.
\frac{ - 6}{ - 12}  =   \frac{ - 12}{ - 12}  + b
-12 cancels out on the right side and your left with
- \frac {1}{2}  = b
Now re-enter the info back into the formula.
y =  - 3x  -  \frac{1}{2}
Then you've got your formula

What is the expression x - 4 represents a negative integer. What integers could X represent?
zlopas [31]
The expression x-4 will come out to be a negative integer. That means X <em>has to be </em>something that when 4 is taken away from it, the answer is still negative.

Let's try 5.
5-4 is 1. Is 1 negative? No, so that doesn't work.
4-4 is 0. 0 isn't negative either, so that doesn't work.
3-4 is -1. Is -1 negative? YES! Let's try it for 2 as well, just to be safe.
2-4 is -2. Still negative.

X can be anything less than 4.
