Use coordinate form, which is y = given slope(x – x-coordinate of given point ) + y-coordinate of given point:
1. y = -4(x – 2) +2
2. y = 2/5(x + 1) +3
3. y = 0(x – 3) – 4
Now, simplify to get to standard form:
1. y = -4(x – 2) +2
y = -4x +8 +2
y = -4x +10
2. y = 2/5(x + 1) +3
y = 2/5x + 2/5 +3
y = 2/5 x + 17/5
3. y = 0(x -3) -4
y = -4

Use y=mx+b format. plug in the slope for substitution for b, and the x and y values for the x and y. Solve for m, and rewrite the equation with the number in its place, only keep the letters y and b as unknowns.
For example, standard format could be: y= 4x+b
