It's pretty simple, first multiple the number, 75x5,105x4,200x3,ect. then add all the numbers uo
(105 \times 4) + (75 \times 5) + (200 x 3) + (105 x 2) + (15 \times 1)

Write the equation of the line graphed below.
posledela

Answer:

y=2x +3

Step-by-step explanation:

The slope hits the points (-1,2) and (0,2). If you count how many units are right and up, then that's your slope. In this case, the distance between those two points are 1 right and 2 up which is the same thing as 2. The y-intercept is 3 since the slope crosses the y-axis there.

Which is the best description for the graph below?<br><br> A graph decreases from (0, 3) to (9, 0).
AURORKA [14]

Answer:

Step-by-step explanation:

As we move from (0, 3) to (9, 0), we see x increasing by 9.  This is the 'run.'

At the same time, we see y decreasing by 3.  This is the 'rise.'

The slope of this line (graph) is m = rise / run = -3/9, or m = -1/3

Since we witness a decrease in y as we move from the first point to the second, we immediately suspect that the slope is negative.
