2) (9,3),(12,18)

3) (-2,-6),(2,22)

4) (0,0),(5,35)

5) (-3,5),(-9,-1)

Answer 1

HI!!

Answer 2

that is a lot of questions !!

Answer 3

@misty1212 hello

Answer 4

lets do this one
(4,7),(2,3)

Answer 5

find the slope by
\[\frac{y_2-y_2}{x_2-x_1}=\frac{7-3}{4-2}=\frac{4}{2}=2\]

Answer 6

@misty1212 its a practice worksheet that I have to finish

Answer 7

then do
\[y-y_1=m(x-x_1)=y-3=2(x-2)\]

Answer 8

solve
\[y-3=2(x-2)\]for \(y\)
\[y-3=2(x-2)\\
y-3=2x-4\\
y=2x-1\] is your final answer
others are similar

Answer 9

2) y=5x-6
3) y=7x+8
