    Finding Polynomial with 2 Roots and a Y-Intercept

    Ok, my calculus teacher is a lunatic and is testing us on every concept we've ever learned in the history of math. How do I do this?? Find the g(x) using a polynomial of least degree. y-int is 16 and roots are -2 and 4 and it's not a quadratic it looks like it goes down then up then down then...

    Proof of y-intercept

    Hi all, I'm working through some problems at the moment and I am a little stuck on an algebraic rearrangement of a coordinate geometry proof. The problem is as follows: We have a line passing through two points A: (x1, y1) and B: (x2, y2) (where x1 doesn't equal x2). Let P: (x, y) be any point...

    graphing: find the y-intercept, need help!

    So i have two point on my graph (2,5) and (-3,-3) the slope is m=8/5 so y=8/5x + b i take the first point so 5= 8/5 (2) + b 5= 16/5 +b afterwards... im stuck can somebody help me figure out the answers plx(Crying)(Crying)

    Finding the Y-Intercept in functions, etc.

    So, to keep my brain energized, I'm relearning some of the Algebra 2 I took this past year. Thing is, my brain only retains something excellently for a month before dropping it. Now I'm relearning functions which sound oddly familiar to me. There is a problem I'm stuck on, and would appreciate...

    Graphing Equations

    Any info on how to solve these would be greatly appreciated! I am in an online math course and it's been years since I've taken a math class so I'm having some trouble. Thanks! 1) Given 5x + 2y = 9, solve for y in terms of x. Then identify the slope of the line and the y-intercept of the...

    Interpret the slope and the y-intercept in terms of the problem?

    A theater manager graphed weekly profits as a function of the number of patrons and found that the relationship was linear. One week the profit was $11,328 when 1324 patrons attended. Another week 1529 patrons produced a profit of $13275.50. I already found the formula and it is y = 9.5x - 1250...

    Determining slope and y-intercept.

    So, the equation that I'm given is this: 7y + 12x -2 = 0 and I'm told to determine the y-intercept and the slope of this line, but I'm not entirely sure how to go about doing that. Any help would be appreciated!
