Answer:
<h2>A. the slope is 8.</h2><h2>A. the y-intercept is 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
y = mx + b
m - slope
b - y-intercept
We have the equation y = 8x + 1.
Therefore:
m = 8, b = 1

Answer:
$23.42
Step-by-step explanation:
- To find the sales tax, you need to 6.5% of $21.99
- To do this you have to times need to turn 6.5% into a decimal, which is 0.065 (i moved decimal point 2 numbers to the left)
- then you do 0.065 × 21.99 which equals 1.42935
- now you have to add 21.99 with 1.42935 = 23.41935
- because of the context of the question, you need the answer needs to be rounded up to the nearest hundredth.
- making the answer $23.42 total
The given formula 
Solve for y means we have to make y alone
\\
Add -10 on both sides, we get

As there is multiplication sign between r and y so to solve for y, divide both side by r

Step-by-step explanation:
Y=4(5)-9
=11
you must follow the formula given
