## anonymous 3 years ago Indicate in standard form the equation of the line passing through the given point and having the given slope.

1. Jack1

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

3. Jack1

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

4. amistre64

standard form is not the same as slope intercept form

5. Jack1

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

6. amistre64

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

7. amistre64

standard from is: Ax + By = C

8. Jack1

but we dont have slope...?

9. amistre64

m = undefined is the slope

10. amistre64

what type of line has an undefined slope?

11. anonymous

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

14. amistre64

so yes

15. amistre64

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
