The equation is y=2x+1.
to find b in y=mx+b you simply look for a point where x=0 which was (0,1) making the y-intercept or "b" equal to 1. to find the "m" or slope plug in any point for x and y. (9)=m(4)+1 is 2=m. so y=2x+1 is your answer.
Answer:
0 if the line is straight it has a 0 slope you can also use y2-y1 and x2-x1 rise over run to double check my answer.
Answer:
72
Step-by-step explanation:
number of children tickets purchased = c
number of adult tickets purchased = a
c+a= 164
(5.10 x c) + (9.40 x a) = 1232
c + a - a = 164 - a
c = 164 -a
(5.10 x (164-a)) + (9.40 x a) = 1232
836.40 - 5.10a + 9.40a = 1232
836.40 + 4.30a = 1232
4.30a = 395.60
4.30a/4.30 = 395.60/4.30
a = 92
c = 164 - 92
c = 72
