These two points are on a straight line (0,6), (8,22). What equation is represented by the straight line

Question

I need help

Answer 1

First find the slope:

 

rise  22 - 6  ₌  16 = 2

 run   8 - 0      8

 

Then substitute the x,y points and b (slope) to find the y-intercept

I'm going to use the point (0,6)

y =  m x   + b

6 = (2)(0) + b

6 = 0 + b

6 = b

 

Now you plug in your slope (m) and y-intercept (b) in the formula:

y = mx + b

y = 2x + 6   This is your answer
