Idon’t need to know how to solve it i’m going to ask my teacher how to tomorrow but for now i need on these

1) slope=3 and y-int.=-5
2) slope=2 and y-int.=-6
3) slope=-6 and y-int.=1/2
4) slope=-7 and y-int.=5/2
5) slope=1/2 and y-int.=7
6) slope=3/4 and y-int.=8
7) slope=-2/3 and y-int.=-1/3
8) slope=-1/8 and y-int.=-3/8
9) slope=2/3 and y-int.=5
10) slope=-2/7 and y-int.=-1
11) slope=-3 and y-int.=6
12) slope=4 and y-int.=7
Hope this helps!

What number of 40% is 410
x * 40/100 = 410
x * 40/100 : 40/100 = 410 : 40/100
x = 410 : 2/5
x = 410 * 5/2
x = 205 * 5
x = 1025
