To make it easier to solve, we can also write this expression as:

Now we will cancel out the like terms to get:

Taking the square root of the terms to get:


Answer:
y = ( 5 / 9 )x + 30
Step-by-step explanation:
y - y1 = m ( x - x1 )
m = 5 / 9
y - ( 5 ) = ( 5 / 9 ) [ x - ( - 45 ) ]
y - 5 = 5 / 9 ( x + 45 )
y - 5 = ( 5 / 9 )x + 25
y = ( 5 / 9 )x + 30
