Math finding equation
posted by thomas .
Can someone explain to me how to find the equation pf the line in the form Ax + By + C =0 if
a) parallel to x=3 and passes through (4, 3)
b)perpendicular to y=4 and passes through (1, 1)
c) passes through the xint of y=2x6 and yint of y=3x+6
If it is parallel to x=3, the slope is undefined (vertical line), so it is an x=constant, in this case, x=4
A=1, B=0, C=4
If it is perpendicular to y=4, then it is a vertical line. X=1
A=1 B=0, C=1
