Question

Medal for best answer!!!!!






Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:

y > 3x + 10

y is less than negative 3 over 4 times x minus 1

Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area.

Part B: Is the point (8, 10) included in the solution area for the system? Justify your answer mathematically.

Answer 1

@foolofatook

Answer 2

2nd equation y<-3/4x -1

Answer 3

I graphed them both using a calculator and know I need to determine weather the lines are dashed or solid

Answer 4

Answer 5

I used this site

Answer 6

you answer the question for both of them?

Answer 7

I dont really know how to answer them

Answer 8

I know where they intersect but dont get the rest

Answer 9

(for the first equation) a. the graph has a positive slope of 3 with a y intercept of 10.
b. no. because the y intercept is (0,10) and can therefore cannot contain (8,10)

Answer 10

and do the same for the other equation

Answer 11

How did you find all that for the first equation?

Answer 12

looking at the graph from the website link

Answer 13

1st line is shaded above the line, and is a dashed line. Positive slope of 3 and y intercept of 10.

2nd equation is shaded below the line, and is a dashed line.

Answer 14

Does this look right so far?

Answer 15

yes. but describe the slope and intercept for equation 2

Answer 16

How can I find them?

Answer 17

intercept= where the line passes through the x or y lines

Answer 18

It passed through -1,-1 right?

Answer 19

slope= y2-y1/x2-x1 using two points on the line

Answer 20

yes. the y intercept is just -1

Answer 21

slope is 2?

Answer 22

slope is 1

Answer 23

Okay thanks alot If I will need more help I will let u know

Answer 24

ok.
