Find the distance from the origin to the graph of 7x+9y+11=0 I have that desmos site up but it isn't helping.
geogebra?
Trig/Pre-Calc
There are 4 options as well a. 0.96 b. 0.98 c. 0.97 d. 0.99
hmmm well... the graph is a line... and has lots of points.... and each point has a different distance to the origin
Hint: Consider a perpendicular line going through the origin.
good job . really well done lol
heheh
anyhow.... I think... oo.... ok @akick31 you've covered slopes I gather?
Yes we have.
|dw:1389304374927:dw|
anyhow, is say... something. some equation so you'd end up with 2 equation, the given one and it perpendicular one recall that on a system of equations with 2 variables the solution is where the lines MEET or INTERSECT that point, where they meet, is the CLOSEST point to the (0,0) on the perpendicular line
because is the STRAIGHTEST PATH to (0,0) thus the closest
