Best ResponseYou've already chosen the best response.1So, all you can do is apply the equation of the slope, defined by: \[m_{a,b}=\frac{ y_2  y_1 }{ x_2x_1 }\] Which, in more simpler words mean: "the difference of the y coordinates divided by the difference of the xcoordinates". So, applying it for the points give, calling the coordinates (10,5) as point "a" and the coordinates (x,9) as point "b", then: \[m_{a,b}=\frac{ 95 }{ x10 }\] But the desired slope is "2", so therefore: \[2=\frac{ 95 }{ x10 }\] So all you have to do is solve for "x".
