Find the slope of each line.

The slope of the line is -5/4

Step-by-step explanation:

19) = Solution :-

5x+4y = 20

Let's keep x's value 0,

so

we get,

5x+4y = 20

or, 5×0+4y = 20

or, 4y = 20

so, y = 5

one coordinate we get (0,5)

Again

Let's keep x's value 4,

we get,

5x+4y = 20

or, 5×4+4y = 20

or, 20+4y=20

or, 4y = 0

so, y = 0

Another coordinate, we get (4,0)

now

slope(m) = (y2-y1)/(x2-x1)

= (0-5)/(4-0)

= -5/4

-5/4

Step-by-step explanation:

a simple way to find the slope of something from standard form is to use the formula -(a/b)

a is the value in front of the x and b is the value in front of the y

this creates the slope

-5/4

that is your answer

entering that problem on the tube might get you an answer

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
