Solve for the missing coordinate above

let

A( 0,0)

B( x,23)> missing coordinate

step 1

find the equation of the line AB

we know that

the slope of the line AB is equal to 1

because the horizontal distance is equal to the vertical distance

slope m=23/23> m=1

with m=1 and point A (0,0)

y-y1=m*(x-x1)> y-0=1*(x-0)> y=x

step 2

in the equation y=x

substitute the value of y-coordinate of point B and find the value of x

point B(x,23)

for y=23

y=x> 23=x

so

the x-coordinate of point B is 23

therefore

the answer is

the x coordinate is equal to 23

only 10/60 isn't equivalent

hope this : )
