That depends. What are you trying to find? The formula for the perimeter? The formula for the area?
5x + 3y = - 53
the equation of a line in ' slope- intercept form ' is y = mx + c
where m is the slope and c the y-intercept
rearrange 3x - 5y = - 15 into this form to obtain m → (subtract 3x from both sides)
- 5y = - 3x - 15 → divide all terms by - 5 )
y =
x + 3 → in slope-intercept form with m = 
given a line with slope m then the slope m₁ of a line perpendicular to it is
m₁ = -
= - 1 ÷
= - 
partial equation is y = -
x + c
to find c substitute ( - 7, - 6) into the partial equation
- 6 =
+ c ⇒ c = - 6 -
= - 
y = -
x -
→ in slope intercept form
multiply all terms by 3
3y = - 5x - 53 → ( add 5x to both sides )
5x + 3y = - 53 → in standard form
Step-by-step explanation:
17) no problem were noticed, just:
reflecting across Y-axis changes the coordinate 'x', no changes for coordinate 'y';
reflecting across X-axis changes the coordinate y, no changes for coordinate 'x'.

Step-by-step explanation:
it is right
An expression which combines variables, numbers and at least one operation is called binomial. Binomial consists of two terms that is separated with at least one operation. Operations may include addition, subtraction, multiplication and division.
