Farah found 6 rolls of blue ribbon and yellow ribbon. each roll of blue ribbon was 10 meters long and each roll of yellow ribbon was 9 meters long. if farah found 58 meters of ribbon in total, how many rolls of each color did she find?
rolls of blue ribbon
rolls of yellow ribbon

Rolls of Blue Ribbon (B)
Rolls of Yellow ribbon (Y)



simplify by (-9), equation (I), we have:











Now, we will replace the found value (B) in equation (I), to find the value of (Y), thus:

B + Y = 6
4 + Y = 6
Y = 6 - 4


Rolls of Blue Ribbon (B) = 4
Rolls of Yellow ribbon (Y) = 2

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!
