Basile [38]

Answer:

Length = 10

Width = 13

Step-by-step explanation:

If the width of a rectangle is 3 units less than the length and if the area is 130 square units, the length is 10 units and the width is 13 units.

Formula: A=wl

Therefore, you have to find what two numbers multiply together in order to recieve 130 units.

A=wl=13·10=130

What is the y and slope intercepts of this table?
Veronika [31]

Answer:

The answer to your question is y-intercept = 22, slope = -6

Step-by-step explanation:

- To find the answer you need to find the equation of the line.

Process

1.- Find the slope

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

x1 = 2       y1 = 10      x2 = 3    y2 = 4

-Substitution

            m = (4 - 10) / (3 - 2)

-Simplifying

            m = -6/1

-Result

            m = -6

2.- Find the equation of the line

            y - y1 = m(x - x1)

-Substitution

            y - 10 = -6(x - 2)

-Simplifying

            y - 10 = -6x + 12

            y = -6x + 12 + 10

-Result

            y = -6x + 22

3.- Conclusion

y-intercept = 22

slope = -6
