Mistake in Second One..

OpenStudy (anonymous):

I think in the second equation, you should multiply the slope to the value of x as well..

OpenStudy (anonymous):

How? for second one and the last one I dont know if I put the right answer

OpenStudy (anonymous):

for the 3rd one y-4=0(x-5) y=4 ? I'm not really sure w/ this

OpenStudy (anonymous):

\[(y-5) = \frac{-3}{4}(x - 4)\] \[y - 5 = \frac{-3}{4}x + 3\]

OpenStudy (anonymous):

y-5 = (-3/4)x +3 y = -3/4x +8

OpenStudy (anonymous):

@rox13kh its said I have to use it s a Point-Slope @waterineyes ok. so the only thing I messes up is -4, it has to be 3?

OpenStudy (anonymous):

Last One will be: \[y-4 = m(x - 2)\] As, \[m = 0\] \[y = 4\] is the answer..

OpenStudy (anonymous):

@waterineyes ok.. so for the last one I just need to put y=4?

OpenStudy (anonymous):

@rox13kh you are doing wrong for second problem..

OpenStudy (anonymous):

Last one is y = 4. @Trexy

OpenStudy (anonymous):

@waterineyes yup, got it thx ^^

OpenStudy (anonymous):

@waterineyes ok I got that part now.. thank you..

OpenStudy (anonymous):

Welcome dear..

OpenStudy (anonymous):

@waterineyes wait.. for the last one I got y=0x-1 because it saying i need to use Slope-Intercept... the one you did, you used Point-Slope?

OpenStudy (anonymous):

How will you find intercept c then in the equation: y = mx + c m = 0 and c = ?? :Let me check..

OpenStudy (anonymous):

Thats the thing I dont know.. Can You ask @lgbasallote, @timo86m or @Calcmathlete or anyone?

OpenStudy (anonymous):

I think you will get like this: \[y = 0x + 4\]

OpenStudy (anonymous):

use this formula y - y1 = m(x - x1) its easier to deal with

OpenStudy (anonymous):

yeah @rox13kh thats wat We used

OpenStudy (anonymous):

what is your q?

OpenStudy (anonymous):

But it is not the Slope Intercept form @rox13kh Slope Intercept form is: y = mx + c..

OpenStudy (anonymous):

How will you find intercept c then in the equation: y = mx + c m = 0 and c = ?? :Let me check.. plug in what you know and solve for c

OpenStudy (anonymous):

y-4=0(x-5) y=4 but the slope is 0

OpenStudy (anonymous):

it is a horizontal line also it is probably undefined.

OpenStudy (anonymous):

noo horizontal line has a slope 0 vertical line has an undefined slope

OpenStudy (anonymous):

This is the line parallel to x-axis.. |dw:1341634639353:dw|
