Answer: A
Step-by-step explanation: The slope of perpendicular lines is opposite reciprocal. In this case the slope would be 4/3. Plug in for x and y, you get -7 for b.
- y = mx +b
- 9 = 4/3 (12) + b
- 9 = 16 + b
- -7 = b
Rewrite the equation --> y = 4/3x - 7
(17.5)(x)=125
Divide each side by 17.5 leaving the equation as x=7.14

Answer:
y = 0.1x + 200
Step-by-step explanation:
Independent variable (y-intercept) = $200
Dependent variable (Slope) = 0.1 (10%)
Why?
Since Dave's salary is fixed, the $200 he is earning is an independent variable. The commission <em>depends</em> on his weekly sales. The weekly sales is said to be "x". Since 10% is a dependent variable, it goes together with x.
