madeleine2 · Answer

i think the answer is y=x-6 but i used an algebra calculation and i have no idea how to get to the answer

idkanything · Answer

3mar is smart and probably knows

3mar · Answer

Well, I am here.

3mar · Answer

Won't be late for any help.

idkanything · Answer

3mar do u know?

3mar · Answer

Yes.

3mar · Answer

The point-slope form of the line that passes through a point (x1,y1) and has the slope m is
$$y-y_1=m(x-x_1)$$

madeleine2 · Answer

yes i know that the formula is y−y1=m(x−x1) 
 but i dont know how to go from there once i plug in the numbers which i think is y--5=1(x-1)but what do you do after this

3mar · Answer

Can you get the slope of the line which is parallel to the line with the slope 1?

madeleine2 · Answer

i dont know how to do that

3mar · Answer

|dw:1477086804075:dw|
for any two or more parallel lines, their slopes are the same.

madeleine2 · Answer

i really dont get this can you just tell me the steps to get to the final equation

madeleine2 · Answer

@3mar

3mar · Answer

If you get the slope from the parallel line, it would be also 1 because the y are parallel and they have the same slope

3mar · Answer

then plug in these two values of slope and point in the form I typed for you

3mar · Answer

$$y-y_1=m(x-x_1)$$
$$y-(-5)=(1)(x-1)$$
$$y+5=x-1$$
$$y=x-6$$
