Please Please someone help. Last question to a 5 part assignment I've been trying to finish.
Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph. Show your work or explain how you determined the equations.
Graph of line going through ordered pairs (0, 300) and (450, 0)

Best ResponseYou've already chosen the best response.0since x is higher on the 450 x2 becomes 450 x1 becomes 0 y2 become 300 y1 become 0 Slope is rise over run m=y2y1/x2x1 where m is the slope After you find slope, tell me

Best ResponseYou've already chosen the best response.00300=300 So the slope is 300/450 You have to reduce it so its 2/3 m=2/3 The point slope form is yy1=m(xx1) or yy2=m(xx2) either one works then bring the y1 over the right side

Best ResponseYou've already chosen the best response.0(y1) is the value used for the y value you are replacing. So, if you had an example ordered pair of, (5,7), the equation would be [y7 = m(x5)], adding the slope to whatever equation you have.

Best ResponseYou've already chosen the best response.0So, if you understand rise over run, first find the slope of the two points, then use point slope form to substitute in your x, y, and slope values. An easy formula for finding slope in a twodimensional coordinate plane is... \[\frac{ y2  y1 }{ x2  x1 }\]

Best ResponseYou've already chosen the best response.0distributing by multiplying the paranthese for example 6(ab) 6a6b

Best ResponseYou've already chosen the best response.0no you multiply the 2/3 by 450 which equals 300 so its y=(2/3)x+300

Best ResponseYou've already chosen the best response.0wow that wasnt that hard. so in the future all i do is find the slope, then do that other formula and then distribute?
