Question 1

You are given the quadratic formula

$y=\simplify[std]{{a}x^2+{c}}$

What is the slope and the y-axis intercept of the line $\simplify{y={m}x+{yc}}$ ?

Slope = Write your answer as a fraction.Expected answer: y-intercept = Write your answer as a fraction.Expected answer:

What is the $y$ -coordinate of the point on the line whose $x$ -coordinate is $\var{xval}$ ?

( $\var{xval}$ , interpreted as $\displaystyle{}$ Expected answer:interpreted as $\displaystyle{9}$ )
