I WILL AWARD BRAINLIEST

Step-by-step explanation:

y = 0.3x + 1

at point A(..., 9) meaning y = 9

9 = 0.3x + 1

9 -1 = 0.3x

0.3x = 9

x = 9/0.3

x = 30

A(30,9)

y = 0.3x + 1

at point B(5, ...) meaning x = 5

y = 0.3(5) + 1

y = 1.5 + 1

y = 2.5

B(5,2.5)

slope = (2.5 - 9)/(5 - 30)

= -6.5/25

= - 0.26

From the slope the graph is negative

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
