Question

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

Point: (7, 4); Slope: 6

(Points : 1)
y – 7 = 6(x + 4)
y – 4 = 6(x – 7)
y – 4 = 6(x + 7)
y + 4 = 6(x – 7)

Answer 1

Answer 2

Here is our standard form for point-slope form of a line:\[\Large\rm y-\color{orangered}{y_1}=\color{green}{m}(x-\color{royalblue}{x_1})\]

And they gave us this information:\[\Large\rm \color{green}{slope=6}\]\[\Large\rm (\color{royalblue}{7},\color{orangered}{4})\]

Answer 3

Do you understand how to plug the information in?
Pssst! Match up the colors :3

Answer 4

oh ok lol ya hold on

Answer 5

y - 4 = 6(x - 7)

Answer 6

Yay good job \c:/

Answer 7

yay :)

Answer 8

ok next what

Answer 9

That's it :o the problem is finished.

Answer 10

oh ok lol i have a 4 more could u help?

Answer 11

ya i could spare a few i think :3

Answer 12

do u want me to open a new question?

Answer 13

Identify the point (x1, y1) from the equation: y + 8 = 3(x – 2)
(Points : 1)
(–2, 8)
(8, –2)
(–8,2)
(2, –8)

Answer 15

This is just like the last one, except in reverse.
It'll be a little tricky since they threw a plus sign at us though.

Answer 16

So remember that our standard form is:\[\Large\rm y-\color{orangered}{y_1}=\color{green}{m}(x-\color{royalblue}{x_1})\]
See how I wrote MINUS y1?
How would it change to positive? How would it change it addition?

Answer 17

the x is 2 and the y is -8?

Answer 18

Yes :) Good good good.
The y would have to be negative!

Answer 19

yay ok a couple more :)

Answer 20

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

Point: (–2, 4); Slope: 5

(Points : 1)
y + 4 = 5x – 10
y + 4 = 5(x + 2)
y – 4 = 5(x + 2)
y – 4 = 5(x – 2)

Answer 21

lol they're all the same XD
I'll bet you can do this one :3
what do you think?

Answer 22

ok give me a sec. I'm asking so u can check :)

Answer 23

y - 4 = 5(x - 2)

Answer 24

@zepdrix

Answer 25

This one is a little tricky,\[\Large\rm y-\color{orangered}{y_1}=\color{green}{m}(x-\color{royalblue}{x_1})\]\[\Large\rm y-\color{orangered}{4}=\color{green}{5}(x-\color{royalblue}{-2})\]So what is happening to the 2 by our x?

Answer 26

IT BECOMES A PLUS SIGN

Answer 27

yes?

Answer 28

or no

Answer 29

yes :) so that's the only thing we need to fix.

Answer 30

oh ok :)

Answer 31

Which equation is graphed here?

algebra unit 7 lesson 8 assessment question 5

(Points : 1)
y – 4 = (x + 2)

y – 2 = (x + 4)



y – 4 = (x + 2)

Answer 33

thats the graph^

Answer 34

Hmm none of your options have a slope value showing.
Did they not paste correctly?
