Answer:

a) 10 y = x

b) 8.5 min

Step-by-step explanation:

a) x - axis = distance

y - axis = time

the line passing through points (10,1) (20,2) (30,3).......

line equation is y - y1 = m (x - x1)

m = (y2 -y1) / (x2 - x1)

= (2 - 1) / (20 - 10)

m = 1/10

y - 1 = 1/10 * (x - 10)

10(y - 1) = x - 10

10y - 10 = x - 10

10y = x

here x represents distance

y represents time

b) for distance of 85 inches

time =

10 * time = 85

time = 8.5 min

What is the slope of (-7,-1) and (3,8)? Pls show your work
kondor19780726 [428]

Answer:

m=\frac{9}{10}

Step-by-step explanation:

To find the slope between any two points, we can use the following slope formula:

m=\frac{y_2-y_1}{x_2-x_1}

Let (-7, -1) be (x₁, y₁) and let (3, 8) be (x₂, y₂). Substitute them into the slope formula:

m=\frac{8-(-1)}{3-(-7)}

Evaluate:

m=\frac{9}{10}

Therefore, the slope between the two points is 9/10.

A printer can print 27 pages in 4.5 minutes. How much time does it need to print 324 pages?
oksano4ka [1.4K]
So if the printer can print 27 pages in 4.5 minutes, then how much time does it need to print 324 pages?
The equation looks like this:
4.5/27 = ?/324

To find the value of ? divide 324 divided by 27 which equals 12. Then multiply 12 x 4.5 because to keep the equivalent, you must do the same to the top as you did the bottom. 12 x 4.5= 54

Answer: So, to print 324 pages, 54 minutes is needed. 
4.5/27 = 54/324

I hope this helps:)
