The equation, 9x-6y=-72 in slope-intercept form is .
An equation is a mathematical statement that shows that two mathematical expressions are equal.
The standard form of equation in two variable is y= mx+b,
where y is the dependent variable
x is the independent variable
a is the intercept term
b is the slope
Given the following equation:
9x-6y=-72.......................1
Convert it into standard format y=mx+b,
Divide the equation by 6,
On multiplying the equation by -1.
On solving, to represent it into standard form:
On comparing it with standard equation,
Slope, m=3/2 and Intercept, b=12
Thus, slope-intercept form is .

Step-by-step explanation:
-4+(-1) A negative number added by another negative number will stay negative.( like a positive number by a positive will be positive.)
Answer:
When the scale factor between two circles is “x” the scale factor between the radius is also “x” and the scale factor of the area is “x^2"
this is only one possible answer. For example, instead of radius, you could have put diameter or circumference.
B) 2x − 3y < 7
C) −3x + 2y > 7
D) 3x − 2y < 7
Answer:
D) 3x − 2y < 7
Step-by-step explanation:
We note that the x- and y-intercepts are about 2.3 and -3.5, respectively.
In "intercept form," the equation of the line can be written ...
x/x-intercept +y/y-intercept = 1
Using the given intercepts, this is ...
x/2.3 +y/(-3.5) = 1
The answer choices suggest that we should multiply this by 7. When we do, we get ...
3x -2y = 7 . . . . the equation of the boundary line
__
The next trick is to figure the comparison symbol. We note that x-values are less than those on the line, and y-values are greater than those on the line. It is convenient to consider the term with a positive coefficient, so we don't get confused with minus signs and reversed comparisons.
As we said, x-values are less than those on the line, so the shaded area is ...
3x -2y < 7 . . . . matches choice D
