Question

Choose the point-slope form of the equation below that represents the line that passes through the point (6, −3) and has a slope of one half.

Answer 1

y − 6 = one half(x + 3)

y = one halfx − 6

y + 3 = one half(x − 6)

x − 2y = 12

Answer 2

its b because thats the only one in point slope form lol.

Answer 3

xD want to help with a few more?

Answer 4

oh shoot, its actually c

Answer 5

y – y1 = m(x – x1)

Answer 6

I'm dumb. was thinking of slope-intercept form.

Answer 7

y + 3 = one half(x − 6) is my answer then?

Answer 8

exactly I'm 100% sure this time. lol

Answer 9

xD

Answer 10

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form.

Answer 11

−three fourthsx + y = 10

3x − 4y = −40

y = three fourthsx + 12

y = three fourthsx + 10

Answer 12

y-4=3/4(x+8)
y=3/4(x+8)+4
4y-3x=36?

Answer 13

say waaa?

Answer 14

well anyway, would have to be b because is in standard form. Ax+By=C

Answer 15

xD I am trying to solve it right now.

Answer 16

hold on.

Answer 17

Yeah, that's what I got, sort of. xD

Answer 18

Choose the point-slope form of the equation below that represents the line that passes through the points (−3, 2) and (2, 1).

y + 3 = −5(x − 2)

y − 2 = −5(x + 3)

y + 3 = −one fifth(x − 2)

y − 2 = −one fifth(x + 3)

Answer 19

y2-y1/x2-x1
1-2/2-(-3)
-1/5 Is slope
y=-1/5x+b
1=-1/5(2)+b
1=-.4b
-2.5=b is y-int

y=-1/5x-2.5

Answer 20

I seem a bit dilapidated. xD

Answer 21

They put it in standard form so
5y=-x-2.5
5y+x=2.5

Answer 22

-y=5x-2.5
-y=2.5(2x-1)
Igive up

Answer 23

xD Thanks for your help.

Answer 24

The equation is of the form
y - y1 = m(x - x1)
(x1, y1) is either of the given points; "m" is the slope.

Find the slope.
m = (y2-y1)/(x2-x1)
....= (1-2)/(2+3) = -1/5
However, this slope is not in any of the options, and I checked my work, so either you mistyped something, maybe one of the points, or the people making the book made a mistake.

Plug in either point for y1 and x1 in the equation. Apparently they used (-3, 2).
y - 2 = -(1/5)(x - (-3))
y - 2 = -(1/5)(x + 3)

Answer 25

lol no one else can figure it out
