Indicate in standard form the equation of the line passing through the given point and having the given slope.
straight line : y = mx + c quadratic line: y = ax^2 + bc + c circular line: x^2 + y^2 = 1
E(3, 5), m = undefined can you help me with this? this is from the first question
you need at least 2 points to work out the equation of a straight line, sorry dude
standard form is not the same as slope intercept form
..."standard ...form..."...u say?
and you only need a slope and a point to define a line. 2 points helps to define a slope is all
standard from is: Ax + By = C
but we dont have slope...?
m = undefined is the slope
what type of line has an undefined slope?
jack, thats all the question gives me tho
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
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
