write the equaion of a line in slope-intercept form if the slope is 1/5 and the y-intercept is -9 explain please

faust18 [17]

Answer:

$y = \frac{1}{5} x - 9$

Step-by-step explanation:

The slope-intercept form is y = mx + b, where:

m = slope

b = y-intercept.

The slope (m) tells you the steepness of the line. It is the average rate of change which measures how the y-value changes for each one-unit change in the x-value. Hence, slope $= \frac{rise}{run}$ . So the given slope of 1/5 means that for every 1 unit change in the y-value, the x-value changes by 5 units (you go up 1 unit, and "run" 5 units to the right).

Next, the y-intercept is the point on the graph where it crosses the y-axis, and has the coordinates, (0, b). It is also the value of y when x = 0. Since you're given the y-intercept of -9, then that means that it is the y-coordinate of (0, b). So, it becomes (0, -9).

Now that we have our slope (m ) = 1/5, and the y-intercept (b ) = -9, we can write the equation of the line as:

$y = \frac{1}{5} x - 9$

(I'm also including a screenshot of the line where it shows the y-intercept of (0, -9) on the graph).

What are the solutions to 3n-1 > 8 or 4n+ 3

Mandarinka [93]

Answer:

n>3

Step-by-step explanation:

Step 1: Add 1 to both sides.

3n−1+1>8+1

3n>9

Step 2: Divide both sides by 3.

3n/3>9/3

n>3

Pleaseee Help me 20 pts

Simora [160]

Answer:

Tax is C 4.12

Tip is E 15.00

total =94.10

Step-by-step explanation:

Tax = bill * tax rate

= 74.98 * 5.5%

= 74.98 * .055

= 4.1239

To the nearest cent = 4.12

Tip = bill * tip rate

= 74.98 * 20%

= 74.98 *.2

= 14.996

To the nearest cent = 15.00

The total bill is

Final = bill + tax+ tip

= 74.98 + 4.12+15

= 94.10
