Need help, 15 through 23. (Slope and y intercept stuff. Also please add where the points would be at, 100 points...)

answer:

I am pretty sure I did my math correctly I know my slopes are correct and my y=intercepts are correct I am just not sure about my points. Hope I helped.

Step-by-step explanation:

15) points (-1,1)

16) slope= -5/2

17) y-intercept= -6

18) points (-1,-6)

19) slope= -8/3

20) y-intercept= 2

21) points (4,2)

22) slope= 5/2

23) y-intercept= 2

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
