Question

CAN SOMEBODY PLEASE HELP.
-9x + 3y = 6
Its in standard form but we have to put it in slope intercept form and i got
y = 3x - 2
is that right..???
And i have to find the vertical intercept (y)
and horizontal (x)

Answer 1

i mean 3x + 2

Answer 2

yes y=3x+2 is correct for the slope intercept form
So in order to find the x and y intercept, you need to set x and y to 0 accordingly so you want to find
(x,0) and (0,y)

so first to find the y intercept. the y intercept is when x =0
so
y=3x+2
y=(3*0)+2
y=2

so x=0, y=2 is your y intercept

now to find the x intercept, set y=0
y=3x+2
0=3x+2
-2=3x
x=(-2/3)

so x intercept is x=-2/3 y=0

Is that clear?

Answer 3

yes my friends were helping me but i didnt know how they got 3x instead of -3x ..

Answer 4

oh okay :)

Answer 5

thanks!

Answer 6

No problem!
