Question

1.persamaan garis melalui titik [-2,1] dan sejajar garis y=3x-5 adalah...
2.persamaan garis melalui titik [-2.-5] dan gradien 1/2 adalah...
please donk bantu!!!

Answer 1

1. y=3×-5
m=3
y-y1=m(×-×1)
y-1=3(×-(-2)
y-1=3(×+2)
y-1=3×+6
3×-y=-1-6
3×-y=-7

2.y-y1=m(×-×1)
y-(-5)=1/2(×-(-2)
y+5=1/2(×+2)
2y+10=×+2
×-2y=10-2
×-2y=8
