Question

Write the slope-intercept form of the equation of the line through the given points. Show your work.

Through: (2,-2) (-5,5)

Answer 1

Do you know what the slope-intercept form is?

Answer 2

Yeah but I got to -2=-3/7920+b
I don't know what to do next @faith2012

Answer 3

I meant -2=-3/7 (2) +b

Answer 4

@Shadowgirl15

Answer 5

You solve it now.

Answer 6

But how do I multiply 2 by the -3/7? @faith2012

Answer 7

-3/7*2/1

Answer 8

Multiply straight across.

Answer 9

\[\frac{ -3 }{ 7 } * \frac{ 2 }{ 1 }\]
=?

Answer 10

That'll give me -6/7 then I subtract that from -2 right? Do I make -2 a fraction to?

Answer 11

@faith2012

Answer 12

You'd add 2 to both sides, and yes. Too make it easier, you'd make it into a fraction with the same denominator as -6/7

Answer 13

Then that means it'll look like this? 2+-6/7 -> 2/7+-6/7=14/7+-6/7=8/7 (?) @faith2012

Answer 14

Yes

Answer 15
