Question

What is the equation of the line that passes through the points (-2, 1) and (1, 10)?

3x - y = -7

3x - y = -5

3x - y = 5

x + 3y = -5

Answer 1

isnt that one of those y=mx+b questions

Answer 2

It's my last question for segment one. D;

Answer 3

oh lucky i need to finish segment one :/

Answer 4

Yes, You'll have to first make all the answer choices look like "y=mx+b" I could do it but it will take about 10 minutes

Answer 5

solve this system:
-2x + h = 1
x + h = 10

after you solve it, you will get the equation of line in the form:
y = mx + h

Answer 6

-3x + 2h = 11?

Answer 7

its not that hard all you have to do is find out whats m x1 and y1 and write out your problem

Answer 8

@Keridavis can you attempt it?

Answer 9

I can yes ma'am

Answer 10

let's take the second equation:
x = 10 - h
substitute on the first one:
-2(10-h)+h = 1
-20 + 2h + h = 1
3h = 21
h = 7

Now plug it back on second equation:
x = 10 - 7
x = 3

so :
y = 3x + 7

Answer 14

3x - y = -5?

Answer 15

or 3x - y = 5?

Answer 16

3x - y = -7

Answer 17

A. Y = 3x +7
B. Y = 3x +5
C. Y = 3x -5
D. 1/3 (-x-5)

Answer 18

3x - y = -7

3x - y = -5

3x - y = 5

x + 3y = -5

Answer 19

@M4thM1nd are you sure thats the correct answer?

Answer 20

i agree with M4thM1nd

Answer 21

100% sure

Answer 22

you can always plug this two given points on that equation and you will see that, indeed it's the right answer
