Answer:
y=1/2x
Step-by-step explanation:
Equations of lines are written in slope-intercept form:
y=mx+b
where m is the slope and b is the y intercept.
The slope is 1/2 and the y-intercept is 0. Therefore, we can substitute 1/2 for m and 0 for b.
y=1/2x+0
Adding 0 onto the end doesn't change the equation and doesn't serve a purpose, so it can be removed from the end of the equation.
y=1/2x
The equation is: y=1/2x

Answer:
16 times
Step-by-step explanation:
13 + 4 +8 = 25 total marbles
(4 is total number of blue marbles, 25 is complete total of marbles)
4/25 times = ?/100 times
Because 25 times 4 is equal to 100, you then multiply 4 by 4 to get 16
16/100 times
