Answer 1

Which is an equation in point-slope form for the given point and slope?

Point: (–2, 4); Slope: 5

A.
y + 4 = 5(x + 2)

B.
y – 4 = 5(x – 2)

C.
y – 4 = 5(x + 2)

D.
y + 4 = 5x – 10

Answer 2

y-4=5(x+2)

Answer 3

i have a couple more can u help or no?

Answer 4

affirmative, I will help.

Answer 5

Answer 10

Given a slope m and a point (a,b), we can find the equation of the line by using the point-slope form:

\[y-b = m(x-a)\]

Plug in what you know, solve for y, and you'll have a form that you're more used to seeing :)

Answer 11

Oh, you don't even need to solve for y on this one.

Answer 12

oh, okay this looks easy now ;P i have a few more

Answer 13

so y-6 = -3/4(x+2)

Answer 14

Not quite. Your point is (2,-6)
so a = 2 and b = -6

Plug them into the formula, and be careful with signs!

Answer 15

y-6=3/4(x-2) ?

Answer 16

thats what i came up with

Answer 17

y-(-6) = (-3/4)(x - 2)

Answer 18

oh... i feel stupid now... but it is not one of the options it gives me so i really don't know what to select.

Answer 19

It is, you just have to remember that subtracting a negative number is actually addition.

y-(-6) = y+6

Answer 20

oh i get it now!!!!!

Answer 21

y+6=-3/4(x-2)

Answer 22

that would be the correct one!

Answer 23

There ya go :)
