Question

What is the x-intercept of the line with the equation

-2x +1/2y = 18

( ? , 0 )

Answer 1

x intercept is found when y=0. So try to sub in that.

Answer 2

WOuld you please give me the answer or just get me close to it?

Answer 3

im 2 tired

Answer 4

yeah sure! so...we put in y=0 and get -->
\[-2x + \frac{ 1}{ 2 }(0) = 18\]
Then we simplify it to -->
\[-2x=18\]
Then divide each side by -2 and get -->
\[x= -6\]
So the y intercept for the equation is
(-6,0)

Answer 5

rewrite the equation to make y the subject y = ?
then set = 0

Answer 6

thx

Answer 7

oops, sorry 18/2 is 9 sorry!!

Answer 8

the "short-cut" i use is to cover the term in y since anything by zero = 0
the you can "see" to solve for x

Answer 9

so its actually (-9,0)

Answer 10

thx for the steps 2

Answer 11

ooh ok

Answer 12

thx @triciaal
