Help??? the last part confuses me.

Select the proper equation in point-slope form for the given point and slope.

Point: (–3, 7); Slope: 4

y – 7 = 4(x – 3)
y – 7 = 4(x + 3)
y + 7 = 4(x + 3)
y + 7 = 4x – 12

What do you think is the answer? Any try.

Guessing doesn't help me...

anonymous · Answer

Maybe the easiest way iof doing this problem is to plug in the coordinates. (-3,7)
There is only 1 equation that satisfies it.

yttrium · Answer

Yep.
It's the same as the problem you posted earlier.
y-y1 = m (x-x1)
y1 = 7
x1 = -3
m = 4
y-7 = 4 (x-(-3))
Therefore, what should it be @HarukaN

anonymous · Answer

y – 7 = 4(x – 3)

yttrium · Answer

Nope. @HarukaN 
Take note, it is x-(-3)

Let's recall a formula wich I won't prove because i'm too lazy:
$$y-y _{1}=m(x-x _{1})$$
where x1 and y1 are the coordinates of the point and m is the slope.
we have a point and the slope, all we have to do is plug them in:
$$y-7=4(x-(-3))$$
and simplifying the (-)(-):
$$y-7=4(x+3)$$

I tried relating this problem to the other one I had with your explaination but i ended up confusing myself @Yttrium
