Answer:
Equation: Y = 5/4x -7
Step-by-step explanation:
y2 - y1
------------- <------------- This is your slope equation
x2 - x1
-----------------------------------------------------------------------------------------------------------------
3 - (-2)
----------
8 - 4
----------------------------------------------------------------------------------------------------------------
3 + 2
----------
8 - 4
-----------------------------------------------------------------------------------------------------------
5
------- <-------------------------- This is your slope
4
--------------------------------------------------------------------------------------------------------
Y = mx+b <------------------ Your second equation
-----------------------------------------------------------------------------------------------------------------
3 = 5/4 (8) + b <---------- Your new equation
-----------------------------------------------------------------------------------------------------------------
3 = 10 + b <---------- You times 5 by 10 and then divide it by 4
-----------------------------------------------------------------------------------------------------------------
- b + 3 = 10 <------------- Subtract b
--------------------------------------------------------------------------------------------------------------
- b = 7 <------------------------ Subtract 3
---------------------------------------------------------------------------------------------------------------
b = -7 <-------------- switch the negative sign
---------------------------------------------------------------------------------------------------------------
Your equation will be:
Y = 5/4 -7
-----------------------------------------------------------------------------------------------------------------
Hope that helps! :)
