<span>A) 11c - 2d = -2
B) c + 8d = 8
</span><span>B) c = 8 - 8d then substitute this into A)
</span><span>A) 88 -88d - 2d = -2
A) 90 = 90d
d = 1
c = 0
</span>
One expression u can use is 900÷30
Round 868 up to 900
and round 29 up is 30
Y=-3x+-1. you subtract (-4)-(-1) =3 and 1-0 and you get 1 . so the slope is 3 over 1 . and the y intercept is -1
