A middle school took all of its 6th grade students on a field trip to see a play. The students filled 660 seats, which was 55% of the total number of seats in the theater. How many total seats were in the theater?

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
