m = (y2-y1)/(x2-x1) = (1-(-3))/(1-(-2)) = (1+3)/(1+2) = 4/3.
4. 24/8 = y/10, Y = 30.
5. Y = (2/3)x + 9.
6. (1,-3), (3,1).
m = (1+3)/(3-1) = 2.
Y = 2x + b = -3.
2*1 + b = -3, b = -5.
Eq: Y = 2x - 5.
2. D. 4/3

2. 4/3
3. 30
4. y=9x

for the point slope form
1.b y-3=6(x-8)
2. the graph for that is a
3. c (3,-4)
