NNADVOKAT [17]

Answer:

m = -3

Step-by-step explanation:

First, find two clear points:

(1, -2) (0, 1)

Then, use the slope formula:

m = <u>y2 - y1</u>

      x2 - x1

m = <u>1 - (-2)</u>

       0 - 1

   = <u>3</u>  = -3

     -1

m = -3

This means that the rise-over-run is -3 over 1, or 3 over -1.

Which means three down and 1 to the right, or 3 up and 1 to the left.

Slope is the steepness of the line.

Whitepunk [10]
5x + 8y = -29
7x - 2y = -67 ..... multiply both sides by 4

5x + 8y = -29
28x - 8y = -268

33x + 0y = -297
x = -9

svetoff [14.1K]

Answer:

50 minutes

Step-by-step explanation:

she spent 1 hr and 30 minutes on homework

she spends 2/3 of an hour on the phone = 40 minutes

1 hr 30 min + 40 minutes = 2 hrs and 10 min

so she had 50 minutes to kill before bedtime since she goes to sleep 3 hrs after dinner

2hr 10 min + 50 min = 3 hrs.
