A printer will produce Katie wedding invitations for $210. The price to produce 120 invitations is $290. The printer uses a line
VMariaS [17]

Thank you for asking this question. Here is your answer:


M = y2 - y1/x2 - X1 = M


= 290 - 210/120 - 80  



M = 80/40


M = 2


Now we will consider y intercept


y = mx + b  


210 = 2(80) + b  


210 = 160 + b  


b = 210 - 160


= 50


Now we will combine everything in order to get the answer.


y = 2x + 50


y = 2(60) + 50  


y = 120 + 50  


y = 170


So the final answer for this question is $170.


If there is any confusion please leave a comment below.
