tolong bantuanya wahai sahabat brainly. soal remedial UAS Matematika

7. m = -A/B
= -10/-4 = 5/2 (A)
8. m = y2-y1 / x2-x1
= 5-(-4) / -3-1
= - 9/4 (B)
9. m = -A/B
= -(-4) / -3
= - 4/3
10. a. 3 / (5-3) = 3/2(A)
11. m = -A/B
= -1/-8 =1/8
-2/m = 1/8
m = -2 × 8 = -16 (E)
12. y=mx +c
m = -7 (D)
13. m= 2 ; c= 4
y=mx +c --> (C) y= 2x + 4
14. m = 4-3 / -1+5
= 1/4
y-4 = 1/4(x+1)
4y-16 = x+1
4y-x-17 =0 (B)
15. m = 4/2 = 2
c = 4
y= 2x +4 (A)
16. m = -1/2
y-4 = -1/2(x-2)
2y-8 = -x+2
x+2y = 10 (B)
17. m = 7 / -7 = -1
y-5 = -1(x+3)
y-5 = -x-3
x+y-2=0 (C)
18. ga jelas gambarnya
19. m= -3/2
y-1 = -3/2(x-4)
2y-2 = -3x+12
3x+2y-14 = 0 (D)

Mohon jadikan jawaban terbaik. Trims
