attention smart people!!!
can anyone solve this for me sorry I'm dumb as shit and this is due in 2 hours. I need the x and y values for these 2 problems tysmmmm if your dumb like me too thats okay lol
So if y = -8x and y-8 = -x then you can sub y with -8x in the second one. So that will make -8x-8=-x which can be simplified to -7x - 8=0 then again to -7x = 8 so -x= 7/8 so x = -7/8. Sub that into y-8=-x making y-8= 7/8 so y= 7/8 +8 = 71/8
Soooo point = (-7/8, 71/8) hope this helps (=・ω・=)
Edit:attached a pic cos I'm a nerd. 2 reply
um lol so im not sure if im correct but..
y=-8x 's x and y values are x intercepts=0,1 and y intercepts=0, -8
and for y-8=-x the x and y values are x intercepts= 8,0 and y intercepts= 0,8 reply
I didn’t even know you could get X and y values from that, I thought you needed a full y=mx+b thing to work it out, idk sis I got as far as 8y= x and idek, good luck reply
Just get y by itself and equal both of the answers to each other. So it would be y = -8x and y = -x + 8
-8x = -x + 8
-7x = 8
X = (-8/7)
Y = 8(-8/7)
Y = -(-8/7) + 8
Y = 9.14 reply
