I think they're asking you for the slope of the line as the tangent of the angle between a line and the x-axis is the slope. Use the formula y2-y1/x2-x1=tan& where (x1,y1) and (x2,y2) are the respective points

they're asking for £
slope equal tan theta
exactly
ahaa , so wait !
so the slope=1. tan£=1 so theta=45°. so no need for another slope, ha !

So they are asking

Thus, 


So the slope =1. tan£=1 so theta=45° 

So no need for another slope.
