Find the equation of the line that passes through the pair of points.then write in slope intercept form

Question

(6,6),(3,4)

y=

Answer 1

Leslie,

Refer to previous answered post and do in the same manner.

 

Find the slope from m = (change in y)/(change in x)

 

Then y = mx + b where m is the slope

 

Plug in one of the given points as (x, y) to find b

 

*****From previous post*****

(-1,-6),(1,-2)

 

Slope intercept form:  y = mx + b

m = slope, b = y-intercept

 

slope:  m = (change in y)/(change in x) = (-2-(-6))/(1-(-1)) = 4/2 = 2

 

y = 2x + b

Using one of the given points as (x, y) solve for b

You can use either, I will use (-6, -1)

 

-6 = 2(-1) + b

-6 = -2 + b

-4 = b

 

Your equation is:  y = 2x - 4
