Find the slope and the y-intercept of the line. - 3x - 4y= -20
Write your answers in simplest form.

Slope:

Y-intercept: 5

Step-by-step explanation:

Linear equations are typically organized in slope-intercept form: , where m is the slope and b is the y-intercept.

To find the slope and y-intercept of the given line, rearrange the equation into slope-intercept form. We can do this by isolating y.

Add 3x to both sides:

Divide both sides by -4:

Now, we can identify to be in place of m, the slope, and 5 to be in place of b, the y-intercept. Here is a comparison:

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.
