Step-by-step explanation:
1. Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work..
2x+3y=1,470
-2x+3y=1,470-2x
3y=-2x+1,470/3
y=-2/3x+490
slope=-2/3
y-intercept=490
Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.
First, graph the x-intercept, and go 2 units down. Then go 3 units right. Continue using the same pattern.
3.Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
f(x)=-2/3x+490
The graph represents the number of Wraps that have been sold, as a correspondence to the number of Sandwiches that have been sold.
4. Graph the function.
y-intercept = 490
x-intercept = 790
5. G(x) = - 2/3 x +531
6. Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph.
The equation is: y = -2/3 + 300. The reason for that is because the slope is -2/3 with the y-intercept being 300.
