Two straight lines perpendicular to each other, the slope of which is negative reciprocal.
y=-4/3x+b
The known points are put into the linear equation
y=-4+b
b=13
y=-4/3x+13
Answer:
x < x and -3x < -3x
Step-by-step explanation:
x cannot be less than itself so there would be no solution.
Answer: Months, x : 15 Total cost, y: $150.00 and $250.00
Step-by-step explanation:
Answer:
