kemiringan garis melalui titik (4,h) dan (h+3,7) dan kemiringan 1/4 tentukan nilai h

1/4 = (7 - h) / ((h + 3) - h)
1/4 = (7 - h) / 3
3 = 28 - 4h
4h = 25
h = 25/4

m = [tex] \frac{ y_{2} - y_{1} }{ x_{2} -x_{1} } [/tex]
[tex] \frac{1}{4} = \frac{7-h}{h+3-4} = \frac{7-h}{h-1} \\ 1(h-1)=4(7-h) \\ h-1=28-4h \\ h+4h=28+1 \\ 5h=29 \\ h= \frac{29}{5} =5 \frac{4}{5} [/tex]
