Question

MEDAL
how would you graph Y = (-2/3)x + 400
??

Answer 1

since you already have the y-intercept as (0,400), all you have to do is to find the x-intercept using the equation of the line taking y=0

Answer 2

what's your x-intercept then?

Answer 3

x = 600

Answer 4

so you'll have the point as (0,400) and (600,0)
you can now plot

Answer 5

okay @shinalcantara , but it says use the slope-intercept method.
how would i do that ?

Answer 6

Y = (-2/3)x + 400
have you remembered slope-intercept form?

Answer 7

is it Y = mx + b ?

Answer 8

isn't it that the form is
y = mx + b
where m is the slope and b is the y-intercept

Answer 9

using that idea you will know that the y-intercept, b, is 400.
then you can say that the first point is (0,400)

Answer 10

okay, so what next ?

Answer 11

since you know that the slope is -2/3 then you'll have it as

Answer 12

ohhhhh thank you!
