please help asap !! ill mark brainliest but be corrrecct

Answer:k=4Step-by-step explanation:Given A line x=7 The line has only y-intercept which means that it is a vertical line. As the two points are A(10,2) and B(k,2) The y-intercepts of both the points are same i.e. y=2 which means that the line fomed by joining A and B is a horizontal line.  As x=7 is a vertical line and bisects the horizontal line, the mid-point of line AB will be the point where first line (x=7) bisects the second which is (7,2). The x-coordinate of mid-point is 7 because the vertical line has 7 as x-intercept and y-intercept is two because the horizontal line has y-intercept 2.So, Mid-point=((10+k)/2  ,2)=(7,2) Comparing the x-coordinate (10+k)/2=7 10+k=7*2  10+k=14 k=14-10 k=4
