A class spends $75 on ingredients and then sells cookies for $5 a dozen. The amount earned y can be represented by the equation y = 5x - 75, where x equals the number of dozens sold.

Describe what the y-intercept and the slope represent in this problem. Please write in complete sentences, include all details and don't forget units in your explanation.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

i agree because i see the other persons thinking is clear

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
