Proportional because the y continues to increase by two while the x continues to increase in intervals of 1
Answer:
(15x- 20) x squared
Step-by-step explanation:
The answer is 25 if you do it on a calculator.
Perpendicular means the slope has to be the negative reciprocal of the slope of the line it is perpendicular to. (0,1) is a y-intercept so you just have to take the slope. Make it a negative reciprocal and plug in the y-intercept in the equation.
y = -8x + 1
The square root of 18 is 4.24
