What would these be in (y - k = m(x - h)) form?

1. Slope = ½; (h, k) = (1, -2)

2. Slope equals 2 and the line goes through the point (-1, 3)

3. The line goes through the points (8,5) and (9, 6)

your point-slope form
y - k = m(x - h)

1. you are given all the necessary data, m = 1/2, point is (1, -2)
y + 2 = (1/2)(x-1)
I would multiply both sides by 2 to get rid of fractions
2y + 4 = x - 1

arrange into whichever form you like

2. same thing

3. first find the slope, then same thing
1. y+2 = 1/2(x-1).

2. Same procedure as #1.

3. (8, 5), (9, 6), (x, y).
m = (6-5)/(9-8) = 1.
y-5 = 1(x-8).
