Question

1.Write the equation of the line which passes through (5, –2) and is parallel to x = 4. (1 point)

Answer 1

The line x=4 has a slope of infinity
so line parallel to it'll also have slope of infinity
Standard equation of a line with slope m and passing throgh (x1,y1)
(y-y1)/(x-x1)=m
y-y1=m(x-x1)
here m= infinity or let m= 1/p where p=0
so
(x1,y1)=(5, -2)
\[y+2=\frac{1}{p}(x-5)\]
multiplying p to both sides
we get
\[p(y+2)=x-5\]
p=0
so
\[0=x-5\]
so
the line is
\[x=5\]
