Question

multiple choice,
Write an equation in point slope form for the line that passes through (-4, 3) and whose slope is 3
1)y – 3 = 3(x – 4)
2)y – 3 = 3(x + 4)
3)y – 4 = -3(x -3)
4)y + 4 = 3(x + 3)

Answer 1

3 = 3(-4) + c

c = 3 + 12

c = 15

Answer 2

y = 3x + 15

Answer 3

im confused, isn't the answer one of the multiple choice?

Answer 4

Solve them

Answer 5

2)y – 3 = 3(x + 4)

Answer 6

i really don't know how man.

Answer 7

y = 3x + 12+3
y = 3x + 15

Answer 8

Lol, y dont u??
havnt u learn them yet??

then how u got this HW?

Answer 9

This is the equation for point-slope form:
\[y-y_1 = m(x-x_1)\]
where
\[(x_1,y_1)\]
is the point given, and m is the slope. Since we are given the point (-4,3), and the slope is 3, we have:
\[x_1 = -4, y_1 = 3, m = 3\]
putting those into the equation we obtain:
\[y-y_1=m(x-x_1) \Rightarrow y-3=3(x-(-4))\Rightarrow y-3=3(x+4)\]
which i believe is answer choice 2.
