1) Determine the slope of the line for the given points (8/9 , -5) (-9/2 , -3)

2)Use slope-intercept form to write an equation of the line that passes through the given point and has the given slope. (3, -9) ; m=4

*write the equation using function notation where y-=f(x)

3)Use slope-intercept form to write an equation of the line that passes through the two given points (7, -2) (-1, 3)

*write the equation using function notation where y-=f(x)

4)Determine the average rate of change of the function on the given interval. Express your answer in exact simplest form.

f(x)=2x^2 +1
