Okay A c t math drilling people Here we go

00:04

Another one for you of the line Why equals a

00:06

x plus three has a slope of one fourth Which

00:09

of the following points does the line passed through Usually

00:18

slope intercept form has given his wyffels mx plus b

00:21

It must be halloween or something Because m looks awfully

00:25

like a today We're not fooled This isn't mission impossible

00:28

After all since the given equations basically in slope intercept

00:31

form we know our slope is a and a equals

00:35

one fourth right That happens to be the slope in

00:37

case anyone was wondering there We're looking for a point

00:40

on the line Why equals one fourth ax plus three

00:42

So let's give process of elimination a shot here Plug

00:45

the coordinates of each answer choice into the lines equation

00:48

And let's just check the result What We're feeling a

00:51

little unimaginative today So let's start with the first choice

00:53

of a there Well if we use x equals to

00:56

that gives us why equals one four times two plus

00:59

three which equals one half plus three Well that value

01:02

is most emphatically not three So to come of three

01:06

is not online A All right Next up Three come

01:10

of five All right let's see Be here Plug x

01:12

equals three into the given equation that gets us y

01:15

equals one fourth times three plus three So that's three

01:18

force plus three And once again that's why value doesn't

01:22

mention the y value of the answer choice So keep

01:25

going moving on to four four So we try x

01:27

equals four one four times for well that's one plus

01:30

three that gets us a force So he asked the

01:33

y value of four matches the answer choice So the

01:36

given line passes through the point four four and the

01:39

answer is c a cz in middle c Yeah that's 00:01:42.944 --> [endTime] what it sounds like
