Answer: 1-9
Your line is in the Slope-Intercept form : y=mx+c where m=9 is the slope.
The line perpendicular will have slope m=−1m=−19

Answer:
7x-13y=-117
Step-by-step explanation:
I don't know how this question wants me to solve it, but I just used the slope intercept form. So first, start off with y = mx+b. Plug in the slope for m, so 7/13. Then plug in your points for x,y which is 0,9. You'll get 9 = b. So then you have y = 7/13x+9. So now you need to change into standard form. So, multiply by the denominator (13) and you'll get 13y = 7x+117. Then move the variable over and you'll get 13y - 7x = 117. But it doesn't fit any, so then just multiply by -1 and you'll get -13y + 7x = -117.
Answer:
90/[10+(3-3-4)]=90/[10+(-10)]
90/(10-10)=90/0=0

Answer:
plays an instrument/plays sports = 0.46
plays an instrument/does not play sports = 0.54
does not play an instrument/plays sports = 0.73
does not play an instrument/does not play sports = 0.27
Step-by-step explanation:
plays an instrument/plays sports = 6 divided by 13
plays an instrument/does not play sports = 7 divided by 13
~ you divide by 13 since the row's numbers add up to 13
does not play an instrument/plays sports = 8 divided by 11
does not play an instrument/does not play sports = 3 divided by 11
~ you divide by 11 since the row's numbers add up to 11
