Question

I need to make sure that I'm correct

A company produces accessories for smart phones and tablets. The profit on each smart phone case is $2, and the profit on each tablet case is $3. The company made a profit of $1,200 on the cases last month. The equation 2x + 3y = 1,200 represents the company's profit from cases last month, where x is the number of smart phone cases sold and y is the number of tablet cases sold.

Change the equation into slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all of your work.

The slope intercept form is y=mx+b.

2x + 3y = 1200
-2x -2x

3y = -2x + 1200
/3 /3 /3

y = -2/3x + 400

Answer 1

that looks good ^^
so whats the slope and y intercept ?

Answer 2

m = -2/3
b = 400

Answer 3

@ganeshie8 there is more to the problem though, can you help me with a few more parts?
