a. m= 5-(-1) / -3-7 = 6/-10= -3/5
b. y-y1= m(x-x1)
y-(-1) = -3/5(x-7)
y+1 = -3/5x + 21/5
dikali 5
5y + 5 = -3x + 21
5y + 3x +5 - 21 = 0
5y+3x-16=0
2.
a. 2x-y= 10 diubah nenjadi persamaan y= mx+c
-y = -2x+10
y = 2x - 10, jadi m= 2
b. y-y1= m(x-x1)
y-5 = 2(x-2)
y-5 = 2x - 4
y-2x-5+4= 0
y-2x-1=0
semoga membantu
