Question

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.

Answer 1

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.

Answer 2

so y= -2/3x +400?

Answer 3

Answer 4

that's it

Answer 5

Describe how you would graph this line using the slope-intercept method.

Answer 6

Answer 7

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...

Answer 8

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
