WILL MARK AS BRAINLIEST❗️❗️ Okay so I know how to do the parallel but I’m having a hard time with perpendicular. I know you’re supposed to do the opposite of what you see but I get it wrong when I get my answer. The sign changes. I would appreciate it if someone would help me with the problem below

The equation of line q is y = 8x - 2. Line r includes the
point (-2, 2) and is perpendicular
to line q. What is the equation of line r?

y = 1/4x + 7/4

Step-by-step explanation:

If the line is perpendicular to another line, the gradient of the perpendicular line would be the negative reciprocal of the first line.

(-1,-0.5)

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
