Question 931914: If you have the points (20,1.2) and (53,2.6) how do you find the slope and how to make the equation of the line? I really need help! :(
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! slope = m = dy/dx
m = (2.6 - 1.2) / (53 - 20)
m = 0.0424242424242
---
point-slope form:
y - y1 = m(x - x1)
y - 1.2 = 0.0424242424242(x - 20)
y = 0.0424242424242x - 0.0424242424242*20 + 1.2
y = 0.0424x + 0.3515
