i dont know how to do it with factions someone help??!!!!
im gonna fail becuase i dont know how to do it
What was the actual question? How to simplify y-9=2/5(x+20 ) ?
"The physicists defer only to mathematicians, and the mathematicians defer only to God ..." - Leon M. Lederman
I guess the question is finding the equation of a straight line whose slope is 2/5 and which passes through the point (-20, 9).
The equation of a straight line passing through a given point (x1, y1) and with a given slope, m, is
y - y1 = m(x - x1).
In the given problem, x1 = -20, y1=9 and m=2/5.
Therefore, the equation of the straight line is
y-9 = 2/5[(x+20)]
5y-45 = 2x + 40
5y - 2x = 85
2x - 5y + 85 = 0 is the required equation.
