Best ResponseYou've already chosen the best response.1first you need to find slope of two points (2,0)(0,1) formula to find slope is \[\huge\rm \frac{ y_2 y_1}{ x_2 x_1 }\] plug in y and x values

Best ResponseYou've already chosen the best response.1yep right :=) now perpendicular slope is negative reciprocal for example if slope of first equation is  a/b then slope of perpendicular equation would be positive b/a

Best ResponseYou've already chosen the best response.1so equation of slope intercept form is y =mx+b where m is slope so substitute m for 2 and pick on of order pair to plug in value of x and y solve for b

Best ResponseYou've already chosen the best response.0Because when i look at the line The y intercept must pass through (1, 2)

Best ResponseYou've already chosen the best response.0So i thought the line would be slanted the other way

Best ResponseYou've already chosen the best response.1perpendicular line passes through the point (1,2) so substitute x and y for (1,2)
