Answer:
The slope is 3/8
Step-by-step explanation:
The difference in the rise (y-values) 3, divided by the difference in the run (x-values) 8, is 3/8.
You can see this by looking at the places where the graphed line crosses the grid, and counting the squares in each direction between those points, or you can use the formula (y - y₁) ÷ (x - x₁)
Using the values of coordinates (3,1) and (-5, 4)
4 -(1) ÷ 3 - (-5)
3 ÷ 8
3/8

i just ended things with someone so im gonna take a break for a day or so, just to try and process whats going on so if you text me and i dont reply im not on brainly ok?
Step-by-step explanation:
Since there are 9 values, to find the Lower Quartile and Upper Quartile, you use the first 4 values and the last 4 values.
For Q1, you average the middle to values of your first 4 values since 4 is an even number. In this case (22+25)/2=23.5.
You do the same for Q3. (32+33)/2=32.5
For the interquartile range, you subtract Q1 from Q3. So, 32.5-23.5=9
Therefore, your lower quartile is 23.5, upper quartile is 32.5 and the interquartile range is 9.
