Suppose that a sales person observed that if an item is priced at $9 per item then 6 items are sold. if 4 items are sold for $11 per item then you find a linear equation to model the number y of items sold for x dollars per item. find the slope-intercept form of the equation of the line.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

the answer to question 1 is -8, 28.

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
