Question

Write the equation of a vertical line passing through the point (3,-9) in slope. Intercept form and in standard form

Answer 1

x=3

in slope intercept form? slope is undefined, = infinity or negative infinity

y intercept doesn't exist either DNE, DNE slope & intercept. y intercept is where the line intersects the y axis, but x=2 never intersects the y axis. They're parallel lines that never meet, ever. except in non-Euclidian space, like longitude lines on earth

y=mx+b

maybe y = +/-infinity(x) +/-infinity, but no one ever writes it that way or even thinks of writing it that way, except with a misleading question given in this problem

standard form?

ax+by= c? translate x=3 to that?

then a=1, b=0, c=3

(1)x +(0)y = 3

x+ 0 =3
