Answer:
Y=3x
Step-by-step explanation:
Direct proportion
Answer:
Last one: 3x²
Step-by-step explanation:
Quadratics are functions with the power of 2 as the highest.
Option 1 is a Reciprocal function
Option 2 is a linear function
Option 3 is a exponential function
Option 4 is a quadratic function
Important fact: The slopes of perpendicular lines are negative reciprocals of one another. Thus, if the given line here has the slope 1/4, the slope of any line perpendicular to it will be -4 (the negative reciprocal of 1/4).
(0,2) is the y intercept of the new line.
Thus, the new line's equation is y = mx + b, or y = -4x + 2.
3:7, Basically simplifying it.
