So WX is 7y +4 and XY is 21, and when you add those lines you get the whole thing, which is 12y so write that like an equation
12y = 7y+4+21
12y = 7y+25
5y = 25
y = 5

Write y=-2/3x-4 in standard form using integers

Scilla [17]

Answer:

Step-by-step explanation:

The standard form of an equation of a line:

$Ax+By=C$

We have:

$y=-\dfrac{2}{3}x-4$

Convert to the standard form:

$y=-\dfrac{2}{3}x-4$ <em>multiply both sides by 3</em>

$3y=-2x-12$ <em>add 2x to both sides</em>

$2x+3y=-12$

2 lines form intersecting at a right angle a. form a line b. are parallel b. are perpendicular c. form a ray

Nonamiya [84]

Two lines intersecting at a right angle would be perpendicular. Parallel lines do not cross or touch each other, and rats don’t form right angles. Perpendicular lines are horizontal and vertical crossing together to form a right angle.
