What are the x and y-intercepts of the line described by the equation? −6x+3y=18.9

Changes made to your input should not affect the solution:

(1): "18.9" was replaced by "(189/10)".

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 

                     -6*x+3*y-((189/10))=0 

 2.1   Subtracting a fraction from a whole 

Rewrite the whole as a fraction using  10  as the denominator :

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole 

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

 3.1     Pull out like factors :

   3y - 6x  =   -3 • (2x - y) 

 3.2       Adding up the two equivalent fractions 
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

 4.1     Pull out like factors :

   -60x + 30y - 189  =   -3 • (20x - 10y + 63) 

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

Now, on the left hand side, the  10  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :
   -3  •  (20x-10y+63)  = 0

 5.2      Solve :    -3   =  0

This equation has no solution.
A a non-zero constant never equals zero.

 5.3     Solve   20x-10y+63  = 0 

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK). 

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  20x-10y+63  = 0 and calculate its properties

Notice that when x = 0 the value of y is 63/10 so this line "cuts" the y axis at y= 6.30000

When y = 0 the value of x is -63/20 Our line therefore "cuts" the x axis at x=-3.15000

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 6.300 and for x=2.000, the value of y is 10.300. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 10.300 - 6.300 = 4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
