Question

Write an equation of the line perpendicular to the graph of x = 3 and passing through D(4, –1).

Answer 1

do u know how the graph of x=3 looks like?

Answer 2

its a verticle line on the x3

Answer 3

correct.... so a line perpendicular to that vertical line has slope = ????

Answer 4

-1?

Answer 5

nope... try again.... slope of a HORIZONTAL line = ????

Answer 6

zero

Answer 7

right.... and since that horizontal line will have y-intercept of -1 (because it has to go through the given point), you equation is y = 0x -1 or simply .....
