Write the equation of the line that passes through (–2, 6) and (2, 14) in slope-intercept form. y = 2x – 2 y = 2x + 10 y = 0.5x + 7 y = 0.5x – 4

    alright, so thats 8/4 which is 2, that was the formula for the slope

    m = 2 now, cause were using M as a symbol of slope... pick an equation, -2, 6 or 2, 14?

    Write the equation of the line that passes through (3, –2) and has a slope of 4 in point-slope form. y + 2 = 4(x – 3) y – 3 = 4(x + 2) x – 3 = 4(y + 2) x + 2 = 4(y – 3)

    alright, we can skip the first part which was y2 - y1 / x2 - x1 cause they already gave u the slope...

    Anne has a total of 3,500 golf balls at home. She loses some golf balls when she goes out on the driving range daily. The number of golf balls, h(x), can be represented by the function h(x) = –150x + 3,500, where x is the number of days she plays golf. Suppose 3,500 changed to 4,000. What does this mean in the context of the problem? Changing 3,500 to 4,000 means the initial number of golf balls decreased. Changing 3,500 to 4,000 means the initial number of golf balls increased. Changing 3,500 to 4,000 means the daily number of golf balls lost decreased. Changing 3,500 to 4,000 means the daily number of golf balls lost increased.

    Im not 100% sure cause it says 3500 is how much she has at home, so in a way its increased, but also decreased cause she can lose em all

    because its the start off amount, the -150x is how much she loses a day
