Question

What is the equation of the line that passes through the point (4,7) and has an

undefined slope?

Answer 1

Explanation:

use the point slope formula

y - y1 = m(x -x1)

where "m" is an undefined slope

and plug in the given point (4,7) it's form is (x1,y1)

y-7 = m(x - 4)

y = m(x - 4 ) + 7
