<span>Jamie bought a hand cover fiction book with $32.99 price.
She has a coupon that has a 15% off.
The store offers 20% off
x= how much will she save?
=> 20% = 20/100
=> .20
=> 15% = 15/100
=> .15
=> .20 + .15
=> .35
=> The amount is 32.99, multiply this by .35
=> 32.99 x .35
=> 11.5465 – She saved $11.55
=> 32.99 – 11.5465
=> 21.4435 – She only paid 21.4435 for her hand cover fiction book that she
bought.</span>

Answer:
you have to use the slope equation, which is (y2-y1) / (x2-x1)
3. (5-0)/(1 -(-8))
5/1+8
5/9
4. (3-3)/(-4 -8)
0/-12
the slope is 0
6. (-2-8)/(1-0.5)
-10/0.5
-20
7. (7-(-1))/ (4-4)
7+1/0
8/0
the slope is undefined
7 x 2/3 = 7/1 x 2/3 = 14/3 = 4 2/3
answer: 4 2/3
The equation of the given line above is y=3x-1. The slope of the line is 3/1 (3x) and the y-intercept which is where the line crosses the y-axis is (0,-1) When you plug these parameters into the equation you will get the equation y=3x-1
Y = -7x - 2
Use the two points given to find the slope (m)
m = (y2 - y1) / (x2 - x1)
m = ( 12-5 ) / (-2 - (-1))
m = -7
Now we have y = -7x + b where 'b' is our y-intercept. We can solve for 'b' by choosing one of the (x,y) coordinate points and plugging them in.
Let's choose the point (-1,5). Plug -1 in for 'x' and 5 in for 'y' and solve for 'b'.
y = -7x + b
5 = -7(-1) + b
b = -2
Final eqn: y = -7x - 2
