## Answers

1) y2-y1/x2-x1 = -5-1/4-2 = -6/2 = -3

2) The triangles are proportional to each other because, the bigger triangles AB(base) to BC(height) ratio is 8:4, which if simplified would be 4:2, and the smaller triangles is 4:2, which is the same. In other words, both of the triangles are the same.

3) y=0.15x, so the slope is 0.15, and each pencil costs 15 cents, or 0.15 dollar.

4) y=55x, where x=5, so y=55(5)=275.

The bus will travel 275 miles in 5 hours.

5) Slope-intercept form : y=mx+b, where m=slope, and b=y-int.

So, C = 15t+4 is the equation.

6) Yes, this graph does show a proportional relationship, because it costs $1 for every 10 photos, and this ratio is same for every amount of photos.

7) y-y1 = m(x-x1)

y-6 = 4(x-4)

y-6 = 4x - 16

y = 4x - 10

8) Olivia: y=2x

Matt: y=3x

Matt travels at a faster rate, and I know this because Matt walks at 3 miles per hour, while Olivia walks 2 miles per hour, and obviously 3 mph is faster than 2 mph.

1. slope is -6/2 which simplifies to -3

4. it will travel 275 miles

3. the slope of the line is .15, each pencil costs 15 cents

thats all ik

According to my circulatory system, you are incorrect because donkeys can fly but oranges can’t lick themselves. i think you should keep that out of your mind next time. you’re welcome!!
