Sales Tax would be considered a) percent increase, because it is an added amount onto the total.
Discount would be considered b) percent decrease, because it takes a certain amount off of your total.
Tip would be considered a) percent increase, because similar to sales tax, you must add it on to your total.
LINE A
y-intercept : 3
x-intercept: 3
Rate of change: x (because 3/3 equals 1 and 1 times x is the same as x by itself)
Line B
y-intercept: 2
x intercept: -2
rate of change : x (because 1/1 is 1 and 1 times x is the same as x by itself)
Line C
y-intercept: -4
x intercept: 2
rate of change: 2
Line A: Equation F
Line B: Equation D
Line C: Equation E
Extra Notes:
y=mx + b is the slope intercept equation.
M is the slope
B is the y intercept
X and Y are the coordinates
To find slope, you can always use y2-y1/x2-x1 or even determine the slope on the graph by using rise over run and simplifying when possible.
