HELP NOW PLEASE!!!
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.

slope intercept form is
y = mx + b
m = slope and b = y-intercept
you need to start by subtracting 2x from both sides of the equation
then divide every term by 3
that will put the equation in slope intercept form.
I'd choose 3 points
x = -3 x = 0 x = 3
substitute each value to get a corresponding y value
you have 3 points plot them and draw a line through them...
but if you want to use the slope and intercept...
plot the y-intercept 400
then from that point fall 2 and run 3 plot the point...
then draw a line through the 2 points
I prefer the 3 point method
hope it helps
