a line with an angle of inclination of 45 degrees passes through (-5/2,-9/2). If the ordinate of the point is 6, what is its abscissa

first find the slope
m= tan£
m=tan 45
m=1

then by using slope formula.
(-5/2,-9/2) (x,6)
m=(y sub 2-y sub 1)/x sub 2-x sub1)
1=(6+9/2)/(x+5/2)
x+5/2=(6+9/2)
x=21/2-5/2
x=16/2
x=8
