Find the slope of the line graph below?

-2

Step-by-step explanation:

Slope if rise / run

So what you want to do is look for two points that are close to each other on the vertical (y axis). This case i'm going with the 7 and the 5

This would give you a rise of -2: since as it move downwards as it goes to the right. (y2 - y1, y2 = 5, y1 = 7 so 5-7 = -2)

Next take the same points but look at them on the horizontal (x axis) and see how long it takes for it to get to the same points.

it starts at -1 and ends at 0.

so run = 1: since it moves to the left (x2 - x1, x2=0, x1=-1, 0-(-1) = 1)

This makes your slope

-2 as you have (-2/1)

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

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
