Learn with an example The points (-4, k) and (-2, -9) fall on a line with a slope of -9. What is the value of k?
k=

If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

Suppose that g(x)=f(x+9) which statement best compares the graph of g(x) with the graph of f(x)

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
