What is the equation of the line that has a y-intercept of 4.5?

a.) y= 4.5
b.) y= -4.5
c.) x= 4.5
d.) y= x-4.5

a) y = 4.5

Step-by-step explanation:

y intercept is where the line crosses the y axis. so y must be 4.5

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

i think it's b
