Question

find the slope and the y intercept of the line
8-1/5y=2x

Answer 1

You want to use algebra to put the given equation into the form

y = (some number)*x + (some other number)

Do you know how to begin doing this?

Answer 2

no clue a little confusing

Answer 3

lizzy - is this 1/5 times y or 1 divided by 5y?

Answer 4

1 divided by 5y

Answer 5

wait 1/5 times y.

Answer 6

ok

Answer 7

\[8-\frac{1}{5}y=2x\]

Answer 8

yes that is it

Answer 9

ok so we first need to multiply every term by 5 to get y:

5*8 - 5* (1/5) y = 5*2x
40 - y = 10x
40 - 10x = y
or y = -10x + 40

now in this form we can pick out the slope and the intercept on y-axis

Answer 10

-10 is the slope and y-axis intercept is the vwlue of y when x = 0

y = -10*0 + 40
y = 40

Answer 11

did you understand the algebra?
