The "m" in y = mx + b is the <u>slope.</u>
It is the number of units a point goes up, down, left, or right each time. Making the line linear/straight.
"rise" is the the number of units you go up(+) or down(-), "run" is the number of units you go to the right
For example, if your slope is:
You are going up 1 unit, and to the right 2 units
3 or 
You are going up 3 units, and to the right 1 unit
You are going down one unit, and to the right 2 units
-3 or 
You are going down 3 units, and to the right 1 unit

Answer:
$27.59
Step-by-step explanation:
1) First we calculate the sales tax:
30 x .15 = 4.5
30 - 4.5 = 25.5
2) Now we calculate sales tax
25.5 x .082 = 2.09
25.5 + 2.09 = $27.59
Answer:
86%
Step-by-step explanation:
<u>430</u><u> </u> × <u>100</u> = <u>430</u> = 86%
500 1 5
you are going to cancel. 100 divided by 100 leaves 1. 500 divided by 100 is 5.
430×1= 430. 5×1=5. divide 430 by 5 and you"ll get 86.
Answer:
7
Step-by-step explanation:
To solve this, we have to work backwards. If you divide something by 9, and it equals 5, to figure out the number, we need to multiply by 9. 5*9= 45. If four was taken away, we have to add it to 45, which is 49. If a number *7 is 49, then we have to divide by 7 to get the answer. 49/7=7
