Some things you need to know:
1) You need to know how to convert standard form to slope y-int. form and slope y-int. form to standard form.
2) When two lines are parallel, the slopes are the same.
3) When two lines are perpendicular, the slopes are negative reciprocals of each other. (Or their product is -1)
example: 3/4 --> -4/3.
3/4 * -4/3 = -12/12 = -1
4) To find the value of b, substitute the point into the equation.
5) Convert the equation to slope y-int. form to find the slope.
6) When a line has an undefined slope, the slope y-int. will look either like
y = __ (forms horizontal line) or x = __ (forms vertical line).
To find the perpendicular of these lines, turn y to x / x to y.
To find the value of __, look at the point located in the line, so if x = ___
passes through (5,3), then x = 5 because x = 5 in the point. So the
equation would be x = 5.

Answer:
Step-by-step explanation:
the answer is 14
Answer:
1. Multiply 6 each time. Equation: 6x = y
2. Multiply 15 each time. Equation: 15x = y
Step-by-step explanation:
Check. Let:
Input = x
Output = y
Put the data into the equation given:
Equation: 6x = y
When x = 1; y = 6
6(1) = (6)
6 * 1 = 6
When x = 2; y = 12
6(2) = (12)
6 * 2 = 12
When x = 3; y = 18
6(3) = (18)
6 * 3 = 18
etc.
Check. Let:
Input = x
Output = y
Put the data into the equation given:
Equation: 15x = y
When x = 1; y = 15
15(1) = (15)
15 * 1 = 15
When x = 2; y = 30
15(2) = 30
15 * 2 = 30
When x = 3; y = 45
15(3) = 45
15 * 3 = 45
etc.

Answer:
You need to ask your question.
Answer:
13 units
Step-by-step explanation:
Because the c term (9 for f(x)) represents the y intercept. The y only moves the graph up or down. Since we are trying to get from 9 to -4 move down by 13 units.
