Question 350791
<font face=”Garamond” size=”+2”>

For the first one, use the point-slope form of an equation of a straight line:


*[tex \LARGE\ \ \ \ \ \ \ \ \ \ y\ -\ y_1\ =\ m(x\ -\ x_1)]


Where *[tex \Large \left(x_1,\,y_1\right)] are the coordinates of the given point and *[tex \Large m] is the given slope.


For the second one, use the two-point form of an equation of a straight line:


*[tex \LARGE\ \ \ \ \ \ \ \ \ \ y\ -\ y_1\ =\ \left(\frac{y_1\ -\ y_2}{x_1\ -\ x_2}\right)(x\ -\ x_1)]


Where *[tex \Large \left(x_1,\,y_1\right)] and *[tex \Large \left(x_2,\,y_2\right)] are the coordinates of the given points.


For the next time you post, read the instruction that says one question per post.  After you have read the instruction, follow it.

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
