Blue ink are equations used to solving the problems.
2 of them is blue because since there is 16 marbles you multiply 1/8 by 2 and 2/16 so 2 marbles are blue
Answer:
y=3x-5
Step-by-step explanation:
First find the slope, 4+2 over 3-1, giving you the slope of three
then set up your equation, y=3x+?
I played with the y=3x - part on the website desmos graphing calculator, I first inserted the points then found the slope and then played with the equation till it went through both the points.
Y - y1 = m (x - x1)
m = 4 , x1 = 1 and y1 = 3, so its
y - 3 = 4(x - 1)
