Question

Persamaan garis ka pada titik (0,-5) dan (10,0) adalah

Answer 1

Verified answer

m = Δy / Δx

m = (0+5) / (10-0) = 1/2

y-y1 = m(x-x1)

y+5 = 1/2 (x-0)

2(y+5) = x

2y+10 = x

x-2y = 10

Answer 2

Verified answer

Y-y1  /y2-y1=x-x1/x2-x1
y-(-5)/0-(-5)=x-0/10-0
y+5  /0+5    =x-0/10
y+5  /    5    =x-0/10
perkalian silang
y+5(10)=x-0(5)
10y+50=5x-0
10y      =5x-50
    y      =5/10x-50/10
    y      =1/2 x-5
