Question

Describe how you would graph this line using the slope-intercept method.

Y= 1 1 /2x +4

Please help me I don't understand how to do this.

Answer 1

so this in form y=mx+b
where m is the slope and b is the y-intercept

Answer 2

so (0,4) is the y-intercept

Answer 3

and slope is m=3/2 ( is that a mix fraction you have there; if so i just rewrote as an improper fraction)

Answer 4

so using (0,4) I would count up three from that point and the count to the right twice
(using our slope)

Answer 5

then I would connect those dots

Answer 6

to draw my line

Answer 7

It 1.5 in decimal form so it is one one half.

Answer 8

ok well i would write it as an improper fraction like i did above

Answer 9

so i'm going to plot the point (0,4) this is our y-intercept

Answer 10

i should have put some more lines oh well
instead of looking at 3/2 we could look at -3/(-2) since
3/2=-3/(-2)

Answer 11

so -3/(-2) means to count down three and over to the left 2 like this:

Answer 12

now we connect the dots

Answer 13

just remember the slope is rise/run
thats how come i knew to fall 3 and go left 2
