I don't get this algebra problem.. Could someone help me understand it?

Question

Okay, im stuck on something on my homework, i dont understand what its asking me..

"Which of the equations below is a formula for y in terms of other variables?

(a) b = y - mx (b) y = mx + b (c) x = y - b"

c is "x=y -b" over "m".. looks like a fraction. w/e.

I dont understand what it is asking me.. Simplify the question or something, use examples if you think it will help.

Answer 1

the answer is 'b'
since it is asking for y in terms of the others, it means it wants y on one side of the equation and all the others variables and numbers on the other side of the equation, so that if you put in actual numbers for all the other variables you could find the value of y without moving anything to the other side of the equation.

Answer 2

Which of the equations below is a formula for y in terms of other variables.

You want to find an equation that says y= Kx +pi. The only thing similar to this is (b) y= mx=b.

x is the variable. m and b are constants. Any equation that says y = x +z + h +C , where x,z,h are variables is what you are looking for. There has to be at least one variable but there can be more than one.

Answer 3

Okay, im stuck on something on my homework, i dont understand what its asking me..

"Which of the equations below is a formula for y in terms of other variables?

(a) b = y - mx (b) y = mx + b (c) x = y - b"
(b) y = mx + b

c is "x=y -b" over "m".. looks like a fraction. w/e.
x=(y-b)/m is a fraction

Answer 4

It is asking you which one is saying " which one solves for y?" and it is the one that has y =

In this particular case it is the slope intercept form of a linear equation,

y = mx + b.

If it were asking you to solve for x, in terms of the other then the equation would say, "which is the formula for x in terms of the other variables..., then you would get the x on the left hand side, and the rest on the other using the rules...

Answer 5

This is referring to finding the y point on a line. All points on a line have (x,y) coordinates. The equation for this is y = mx + b. Here are what the components of the equation mean:

m is the slope of the line. Examples: If m is zero, it is a flat line; if it is a positive number, the line tilts up to the right like a clock hand pointing at 1:00; if it is a negative number, the line that tilts up to the left like a clock hand pointing towards 11:00.

x is the x coordinate for any point on the line.

b is the y-intercept. This is the point where the line crosses (i.e. intercepts) the y axis.

Hope this helps.

Answer 6

Its asking you to choose which equation has y in terms of other variables, this means y on one side of the equals and anything on the other side.
In this case the answer is b) y=mx+b
y on one side then mx+b on the other.

Answer 7

When it says, "y in terms of other variables" it means "y is set off by itself on one side of the equation, and the other variables are on the other side."

Or, more simply:
"Someone has gone to the trouble of solving for y."

In the examples above:
a) b is set aside, so this equation is a formula for b in terms of other variables.
b) y is set aside
c) x is set aside.

Therefore, b is the answer.

Answer 8

They're just asking which equation has y all by itself on one side. This is what "in terms of other variables" means.

Therefore, the answer is b.

Answer 9

translation tip:
"formula for y" means "y = "
"in terms of x" means (some expression of x)
example: mx +b
"other variables" mean x, m, b, etc

so,
(formula for y) (in terms of other variables) means
Y = (some expression of (other variables) )
Y = (some expression of (x, m, b) )

Essentially, what it asks you to do is
To find an equation Y
Y = some expression of (x,m,b)

the answer is (b)
y = mx + b

Answer 10

The answer is b.

You are basically being asked to isolate the y on one side of the equal sign, with the other variables on the other side. This is what they are asking when they want you to express y in terms of other variables.
