Question

y = 8.7x + 5

Answer 1

Hello!
What would you like to do with this? :)

Answer 2

i need an answer

Answer 3

Like do you need to find a point that's on the line?
or get this equation into standard form?

Answer 4

get it in a standard form

Answer 5

okay :)
so standard form is ax + by = c
where a b and c are integers
so you need to get all the terms with variables to one side

so for y = 8.7x + 5
subtract both sides by 8.7x and what would you get? :)

Answer 6

y=-3.7x

Answer 7

not quite :)
y = 8.7x + 5 minus 8.7x from both sides
-8.7x -8.7x
-8.7x + y = 5 is what you get, follow so far? :)

then to get rid of decimals you need to multiply each number by negative 10
so like -8.7x times -10 = 87x
y times -10 = -10y
and 5 times -10 = -50

so you have 87x - 10y = -50

Answer 8

thanks alot

Answer 9

Glad I could help :)

Answer 10

y = 2x +3.3 in y intercept

Answer 11

the y intercept can be found when x=0
so solve for y
when y = 2(0) + 3.3
