For the line that has a positive slope, the equation is y = 2x - 1
This is because slope is rise over run(rise/run) or m = y₂-y₁ / x₂-x₁. The line goes up(rise) 2 units, and goes to the right(run) by 1 unit.
The y-intercept(the point the line touches when x = 0) is -1.
You use the equation y = mx + b, try to find m and b(y-intercept) and plug it into the equation.
For the line that has a negative slope, the equation is y = -x + 5
Answer: 6
That chart is confusing ash, but median just refers to the middle value. Just put them in order (4,4,6,9,12) and then find the middle. In this case it's easy as there are an odd number of values. But if you have another question where there are an odd number, for example (4,4,6,10,12,15) find the two middle numbers, 4 and 9, add them (6+10=16) and then divide by 2 to find the number in between those two. (16/2=8)
Hope this helps!
