Two points

1. The mods usually cut duplicates when they are listed. I hope this is not deleted before you see it.
2. The 12 points are good enough.

Givens

• x2 = 50
• x1 = 20
• y2 = 430
• y1 = 190

Formula

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

Solution

• m = (430 - 190) / (50 - 20)
• m = 240 / 30= 8

Equation

(y - 190) = 8(x - 20)

Question

if x = 130 what will y be?

• (y - 190) = 8(x - 20)
• x = 130
• y - 190 = 8(130 - 20)
• y - 190 = 8(110)
• y - 190 = 880
• y = 880 + 190
• y = 1070
