Question

What is the equation of the given line in standard form? Use integer coefficients. y=-1.7x+8.5

Answer 1

A. 17x+10y=85
B. -17x+10y=85
C. -17x+10y=-85
D. 17x+10y=-85

Answer 2

example :
if a = 0.4
10 a = 4

If you want to shift the decimal point to right, multiply by 10

Answer 3

first multiply everything in the equation by 10 to get rid of the decimal. Try that first...don't forget to multiply EVERYTHING by 10.
So what did you end up with ?

Answer 4

\[10y=-17x+85\]

Answer 5

Let me set it up and maybe it will be easier...
(10) y = (10)-1.7x + (10)8.5.......do the math and what do you end up with ?

Answer 6

correct...
10y = -17x + 85...but we need it in standard form Ax + By = C

so add 17x to both sides and what do you get ?

Answer 7

10y+17x=85

Answer 8

well 17x+10y=85

Answer 9

yep...or 17x + 10y = 85...answer choice 1

Answer 10

yay thank you so much!!

Answer 11

sure thing :)
