How do I find the equation of a line that passes through (-4,9) and has no slope?

Question

Can someone please help me??

Answer 1

Y=mx+b is the equation for a linear line.

if it has no slope, then m=0.

-4 is the x value and 9 is the y value.  if the y value never changes (there is no slope, right?) then the y intercept (b)=9

so the equation is y=0x+9, but since 0 multiplied by anything is 0, then the equation is actually y=b.

x=-4

Answer 2

you plug in 9 for y and -4 for x in the y=mx+b formula(the m is slope(0)) !

Answer 3

the line equation is x=-4

When there is no slope, the line must be vertical, and in the equation, the y(vertical) can be anything.

Answer 4

the equation is X=-4.

Answer 5

The only time a line has no slope is when it is vertical. Therefore, your line will be x = something. Because it has to go through (-4,9), the equation must be x = -4.
