Indicate in standard form the equation of the line passing through the given point and having the given slope.

Question

jack1 · Answer

straight line :
y = mx + c

quadratic line: 
y = ax^2 + bc + c

circular line:
x^2 + y^2 = 1

anonymous · Answer

E(3, 5), m = undefined 
  
can you help me with this? this is from the first question

jack1 · Answer

you need at least 2 points to work out the equation of a straight line, sorry dude

amistre64 · Answer

standard form is not the same as slope intercept form

jack1 · Answer

..."standard ...form..."...u say?

amistre64 · Answer

and you only need a slope and a point to define a line.

2 points helps to define a slope is all

amistre64 · Answer

standard from is:  Ax + By = C

jack1 · Answer

but we dont have slope...?

amistre64 · Answer

m = undefined is the slope

amistre64 · Answer

what type of line has an undefined slope?

jack, thats all the question gives me tho

amistre64 · Answer

solving the stadard form for y, we get the slope intercept form
$$ax+by=c$$$$y=-\frac abx+\frac cb$$
given that m = -a/b  is undefined would suggest that b=0

Ax + 0y = C
Ax = C  is the line of an undefined slope

amistre64 · Answer

so yes

amistre64 · Answer

using the point (3,5)

Ax = C

A(3) = C  ,  when C/A = 3  in simplest form A would equal 1 giving us:  C = 3

therefore the equation of line of an undefined slope at (3,5) is:

x = 3
