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
