Best ResponseYou've already chosen the best response.0y  7 = 5/2(x + 4) you need to rearrange this to the form y = mx + b

Best ResponseYou've already chosen the best response.0first add 7 to both sides then distribute the 5/2 over the parentheses finally simplify the right side

Best ResponseYou've already chosen the best response.05/2 is the slope of the line and 3 is the intercept on the yaxis

Best ResponseYou've already chosen the best response.0though it is better to write it as y = (5/2) x  3 as it could be interpreted as 5  2x  3

Best ResponseYou've already chosen the best response.0Which is the equation for the line perpendicular to y space equals space minus 5 over 3 x space plus 11 1 third and containing P(2, 3)?

Best ResponseYou've already chosen the best response.0y = (5/3) x + 11 1/3 the slope of this line is 5/3 so the slope of the line perpendicular to it = 1 / (5/3) = 3/5

Best ResponseYou've already chosen the best response.0i'm a bit confused here  the line which is perpendicular contains the point P (2,3)  right?

Best ResponseYou've already chosen the best response.0ok so we need to use the general form of the pointslope equation y  y1 = m(x  x1) where m = slope (3/5) and (x1,y1) = (2,3) plus these values into the above formula

Best ResponseYou've already chosen the best response.0(if the slope of a line is m then the slope of a line perpendicular to it is 1/m)
