Question

Can someone please answer these for me I’m very confused. I need the answers by 20 minutes

Answer 1

Answer:

12) y = 2x + 8

13) ( -4, 3)

14) y + 3 = 1(x + 2) ; y = x - 1

Step-by-step explanation:

12) ( -2, 4) and (1, 10)

m=(y2-y1)/(x2-x1)

m= (10-4)/(1+2)

m=6/3

m = 2

y - y1 = m(x - x1)

y - 4 = 2(x + 2)

y - 4 = 2x + 4

y = 2x + 8

13)

y - y1 = m(x - x1)

y - 3 = 2(x +4)

( -4, 3)

14) ( -2, -3) and (4, 3)

m=(y2-y1)/(x2-x1)

m=(3+3)/(4+2)

m=6/6

m=1

y - y1 = m(x - x1)

y + 3 = 1(x + 2)

y + 3 = x + 2

y = x - 1
