What is the average rate of change of the equation y=2x^2-4x+6 between f(2) and f(4)

How many 2/5s are in 1 and 1/2 plz someone me right now

4. (10.03 mc) the equation of line cd is y = −2x − 2. write an equation of a line parallel to line cd in slope-intercept form that contains point (4, 5). (4 points) y = −2x + 13 y = negative 1 over 2 x + 7 y = negative 1 over 2 x + 3 − 2x − 3

Ineed to know how to write question one in mathematical terms
